I am part of a group of four women teachers traveling to a conference in Orlando and then spending three days at WDW. I have a town car booked with Tiffany. My question is: If we each bring one large suitcase and one small carry on (4 of each) will all that luggage plus the four of us plus the driver fit in that town car ?? Tiffany knows we have four people, but I am wondering if we should have booked a van.
