Pete,
We timed it just about right. Got on a few minutes before sunset so had a decent view of the surroundings with some sunlight remaining and then saw a decent view of the lights. The cars/pods or whatever the heck you call 'em, were big enough to move around and gain access to all the windows. We did see the all-you-can-drink party car loading and it was packed. Looked like only one bartender, too. I wouldn't imagine you would get more than one or two drinks during your ride. However, I've never verified that. Have fun.
