Limo Question

How long do you typically book the limo for? Our church is at 3 and our reception is at 6:30 or 7 (we still havent decided). And can you FM me pricing you have received? We are trying to only do one limo or bus for our bridal party of 14 plus us. Is it even possible? I would assume we would send the limos home after they drop us off at the RH and then we would go home by the shuttles going back to the hotel.
