Vehicle size only makes sense after the route is clear. A short downtown night with two stops needs a different plan than a Hill Country winery day, a wedding shuttle, or an airport transfer with luggage. The same headcount can fit a sprinter on a hotel-to-ceremony run and need a larger party bus when the group is standing, moving between bars, and carrying coolers.
Share the pickup point, stop order, timing windows, passenger count, and return plan before locking a vehicle. That keeps the quote tied to the trip you actually want to run. Vague requests produce vague options; a rough but honest stop list produces vehicle choices that match comfort, hours, and logistics.
Austin traffic, venue load zones, and event closures change the clock. A route that looks short on a map can still need buffer time for parking restrictions on 6th Street, photo windows at a wedding venue, or post-show exits at Moody Center or ACL. Putting those constraints in the request up front is what turns a general inquiry into a usable written quote.
