Charter bus and shuttle pricing in Sonoma County is driven by three factors: vehicle size, total hours billed, and the date and season.
Standard hourly rates for a 14-passenger Sprinter start around $135–$165 per hour with a 4-hour minimum. A 27-passenger shuttle runs $165–$210 per hour. A 40-passenger mini coach is $195–$240, and a 56-passenger highway motorcoach is $215–$275 per hour.
Wedding shuttle packages are typically billed as a flat fee for a defined service window — for example, 6 hours of continuous shuttle service from 4pm to 10pm. Most Healdsburg weddings run two vehicles for 5–7 hours each.
Peak Saturdays in May, June, September, and October book out 6–12 months in advance and carry a 10–20% premium. Sundays and weekday weddings are meaningfully cheaper.
Always ask whether a quote includes fuel, gratuity, and tolls. Industry-standard gratuity is 18–20% of the base fare and is the single largest line item people forget to budget for.
