What type of price range are you looking for? Most (black car service) SUV's in Miami only offer up to 4 seating. Super Shuttle has an upgraded Mercedes Sprinter Van for $80 to $90 (depending on zip code) exclusive that will seat 9. If booking online, use reservation type VEC or you can request at the curbside kiosk without a reservation. Usually there is a discount given if you book roundtrip (cannot be done at the kiosk), call 305-871-2000 for details.
