All the shows and most of the resturants at the Venitian are great. Perosnally, I'd see Jersey Boys, but Phantom and Blueman are great also.
The best show in town to me is "O" over at Belagio, which you need to vist anyhow. I loved the Elvis guy (Trent something?) down at the Shara(don't bother going there for anything else...slimy)
The Wynn is a good place to vist and the SW Steakhouse is to my mind the best in Vegas. it's my favorite in Vegas...like the atmosphere.
I like some of the off strip places, esp. Palms, Orleans, Rio and Red Rock. Great views of the Strip at night can be had from all of those but Red Rock.
Downtown if fun to just hangout, walk under the Freemont Experince thing...Great free Saxaphone show and other artist hang out there. Check out "Hugo's Cellar" in the Four Queens...excellant. Gold Nugget is good for some short-short gambling. Keep your wallet in your front pocket and your hand in that pocket.
But, just get out at night and walk the Strip, maybe take a cab down to Luxor( very cool) and Mandalay Bay(OK Great Bar in center of casino), come up to MGM(David Copperfield...fantastic show) and NYNY( intersting, but see others first), wander up to Planet Hollywood( again see others first), Paris( interesting but see others first) and Bellagio(a must), Must go to Caesars(everyone has to go at least once in their lives)...skip Harrahs and Imperial Palace and all the trash dives on that side of the street, maybe see some Treasure Island if you have time and Mirage fun also.
Unless your staying there with kids, I see no reason to go the Circus Circus...a dump.
But, if you just want to relax, enjoy a fine hotel, messages, great resturants and food...frankly, you don't even have to leave the Venetian.
Oh, Oh, almost forgot... singing impressionest Danny Ganns at Mirage and singing impressioist ventrilquist Terry Fanter at Caesars....both KILLER SHOWS.
