Vegas is my second home
and I grew up there.
My first choice of hotels is The Mirage or Bellagio. 5 star resorts with fabulous ammenities.
Excalibur is cheap but too "kid" oriented, and not the best service.
Mandalay Bay is too far on the end of the strip.
Luxor is also nice, but not the best location and it's coolness wears out quickly. They do have a good buffet and is the home to Blue Man Group.
MGM - too big and expensive.
NewYorkNewYork: is ok, but too crowded.
Bally's is mediocre, as is The Sahara, Circus Circus I would NOT recommend.
Desert Inn is very classic.
The Aladdin just remodeled so I would not know. Is a mainstay of the strip - one of the originals.
Paris is nice, as is the Venetian, but you might as well stay at Mirage.
Monte Carlo is not as nice as you would think for the price.
My top choices: Mirage, or Bellagio, if tight on funds stay at Treasure Island.
Hope this helps.
