Our yard is in South San Francisco, roughly 70 minutes from Sonoma Plaza on US-101 and CA-37, and every vehicle that runs the valley is one we own and maintain ourselves. No marketplace, no subcontractor, no 20–40% broker margin. The dispatcher who prices your day is the one who assigns the driver who shows up for it.
CPUC TCP 0037963 · USDOT 3126263 · commercial auto liability on every coach · certificates of insurance issued same business day.

Distances are road miles from Sonoma Plaza. Times are typical off-peak on Highway 12 and CA-121. These are runs we stage through the valley week in and week out, not keywords.
| Trip | What it usually looks like | Miles | Drive | Best vehicle |
|---|---|---|---|---|
| Sonoma Valley tasting loopsBuena Vista, Gundlach Bundschu, Ram's Gate, Cornerstone | Four to six stops on a single loop, laid out so the driver never has to reverse a full-size coach out of a gravel lane. Most valley properties take a motorcoach, and we confirm the handful that do not. | 3–18 | varies | 56-pax coach |
| Up-valley runs to Glen Ellen and KenwoodHighway 12 north through Boyes Hot Springs | Highway 12 is scenic and narrow in places, so we send the size that fits the destination rather than the size that fills the seats. Small parties usually end up on a minibus by choice. | 7–12 | 15–20 min | 24–35-pax minibus |
| Vineyard weddings and rehearsal dinnersRam's Gate, Cornerstone Sonoma, Plaza-area inns | Guests from the inn block to the ceremony, then a shuttle running on a loop until the last person leaves. Late nights are the norm here and we quote the hold rather than cutting the night short. | 2–12 | varies | 24–35-pax minibus |
| San Francisco pickups over the Golden GateUS-101 north to CA-37 and CA-121 | City hotel lobbies in the morning and back across the bridge by evening. We build the return around CA-37 traffic, which is the piece of this route that actually decides your arrival time. | 45 | 65 min | 56-pax coach |
| Cross-valley days into NapaCA-121 and CA-12 through Carneros | Two valleys in one day is a common request and it works, but only if the itinerary respects the twenty-odd minutes between them. We build the stop list so the group is not eating lunch in the aisle. | 14 | 25 min | 56-pax coach |
| Plaza events and film festival shuttlesFirst Street East bus zone, Sonoma Mission, Depot Park | Venue-to-venue loops during festival weekends, staged off the First Street East bus parking so the Plaza itself stays clear for pedestrians. | 1–5 | 10 min | 24–35-pax minibus |
| Corporate retreats and team daysValley resorts, tasting rooms, Carneros meeting space | One coach that stays with the group from the first session to the last pour, so nobody is counting rideshares at the end of the evening. Programs of two days or more include a driver overnight line. | 5–30 | varies | 56-pax coach |
| SFO and OAK arrivals into Sonoma ValleyCA-37 from either bridge | Groups landing together with checked bags, met at the curb by a coach with luggage bays. The flight is tracked and the hold is priced, so a delay does not turn into a second dispatch. | 50–55 | 60–75 min | 56-pax coach |
Not on the list? Any group of 10 to 69 out of Sonoma, Glen Ellen, Kenwood or Boyes Hot Springs, anywhere in Northern California. Describe the trip and dispatch will price it.

Most sites ranking for "charter bus Sonoma" do not own a single vehicle. They resell operators like us and add a margin. Here is what changes when you skip that layer.
| Question | Umbrella Global Bus | Booking marketplace |
|---|---|---|
| Who owns the vehicle? | We do. Titled, insured and maintained by Umbrella. | A third-party operator assigned after you pay, often unnamed until day-of. |
| Who is driving? | Our employee, in our DOT drug-and-alcohol program, known to our dispatch. | Whoever the assigned operator sends. |
| What is the price built from? | Our operator rate, itemized: hours, deadhead from South San Francisco, tolls, gratuity. | An operator's rate plus the platform's margin, typically 20–40%. |
| Who answers at 5:40 a.m. when the bus is late? | The dispatcher who assigned the driver, with the coach on GPS. | A call center that has to phone the operator. |
| Certificate of insurance for a venue or employer? | Issued by us, usually same business day. | Requested from the operator through the platform. |
| Can I track the bus? | Yes, a live tracking link for every trip. | Depends on the operator. |
Ranges are published so you can budget before you pick up the phone. The Sonoma quote is itemized to the hour and the mile, including the run up from our yard, and it holds once you book unless the itinerary changes.
Driver included. Five-hour minimum, so a half day runs $750–$875. Valley tasting loops, wedding guest runs, Plaza event shuttles.
Driver included. Quoted per itinerary on top of the hourly rate because deadhead, tolls and return time change the total.
Contract rate for repeating valley routes: resort guest shuttles, seasonal event loops and staff runs, billed monthly.
Always included: driver, fuel, standard insurance, live tracking. Quoted separately: tolls, parking, driver overnight on multi-day trips, gratuity if you choose to add it.
A half-day (5-hour) 24-35 passenger minibus in Sonoma typically runs $750–$875 with the driver included. A 56-passenger motorcoach is quoted per itinerary, since the stop list and how late the group runs matter more here than raw mileage. The quote comes from our dispatch office and is itemized line by line.
Yes, and it is one of the most common requests we get. CA-121 and CA-12 through Carneros put the two valleys about 25 minutes apart, so a realistic day is three stops on one side and two on the other. We will tell you when a proposed stop list does not fit the clock instead of booking it and rushing you.
San Francisco (SFO, about 55 road miles by CA-37), Oakland (OAK, about 50 miles) and Charles M. Schulz Sonoma County (STS, about 35 miles) when a group flies in regionally. Bags go in the luggage bays, not on laps.
The actual bus company. Umbrella Global Bus owns nineteen vehicles, employs the drivers, runs its own dispatch and shop, and holds CPUC TCP 0037963 and USDOT 3126263. When you call, you reach the operator directly rather than a marketplace that resells the job.
There is bus parking on First Street East, which is where we stage for Plaza pickups and drop-offs. For wedding and festival work we agree the load zone with the venue in advance so the coach is not idling in a travel lane while guests board.
Yes. All three of our 69-passenger double-deckers have a wheelchair lift and restroom, and one of the minibuses is lift-equipped for the tighter valley driveways. Tell dispatch how many wheelchair positions you need so the right unit is assigned from the start.
