you could also opt for a "in-suite reception"
pick your favorite hotel, book a suite with a beautiful strip view, bring in catering, plug in your i-pod in the surround system and party all night-long.
An "After-party" can be anywhere. The easiest option would be a nightclub in the various hotels.
Don't forget photography, flowers and the cake!
