Hi. I've been to Vegas several times and stayed at a different resort each time. So far, for the price and experience, Monte Carlo was the best. My husband and I went right after he came back from Iraq one time and we wanted a soothing, romantic atmosphere. Our room at Monte Carlo wasn't the standard room, it had a whirlpool tub for two in the room (by the window looking at the strip) in addition to the bathroom with a steam shower! Whoo hoo. It was a really nice room and the price was the same as a standard room at the other 'big theme' hotels.
The only downside to Monte Carlo, if you consider it one (which I didn't), is that they don't have a mall inside their building. They have just a few shops and a few places to eat. The casino is nice and clean and looks upscale, but had a variety of min. tables. It is also centrally located and Lance Burton was great.
Harrah's was okay - we got to wake up a 8 AM everyday to construction noises.
Riviera was not okay -
It was our first trip and paid for by someone else.
Golden Nugget was great - very nice, but we still like spending time on the strip.
Venetian and Ceasar's would probably be among my top choices. Paris is nice, but wasn't for me.
If Rita Rudner is there, you should definitely see her. She has been the best show for the money. You're in a small(ish) room and she's hysterical.
The intimate setting really gets the audience into it and she has a clean act.
Blue Man Group was great too, but a lot more $$.
That's enough. HTH
Have a great time! Take your swimsuit -it's gonna be hot. 8)
