We came to Party Tours as a large group - 32 people - and were not told that everyone would not be in the same bus. (They could only accommodate 28 in a bus.) This would have been a tolerable issue if the overall experience was fun; it wasn't. You spend the majority of your time waiting in lines or walking to lines instead of hanging in clubs or drinking on the bus. This is a really bad way to waste your money in a city that is very good at wasting your money.
