At the Venetian they have the Gondola ride, don't do the outdoor one. It sucks! There is a wait for the indoor one but it's ten times better than the outdoor one. I also suggests going up the Eifel Tower at Paris at 8:30 or so, the fountains at the Bellagio run every 15 minutes and it's the best view. If you are into Helicopter rides. Maverick does a great tour for under $70 a person. If you want any more ideas, just ask.
