Not any different than what you've read above.Any thoughts would be helpful!
Vdara is not part of Aria. It's part of the CityCenter project, which includes Aria, the Mandarin Oriental, Crystals, and Vdara. Vdara is actually across the street from Aria.I would suggest Vdara at Aria. Vdara has no casino and is a beautiful hotel! Mandalay Bay has the Four Seasons, also with no casino, I believe. And the Signature at MGM. If the casino isn't an issue I would suggest MGM or Aria for their locations, NY NY is also fun for kids.
Excalibur and Circus Circus are both kid friendly but very run down. I would not stay at either hotel. I would not even visit Circus Circus!
Tahiti Village is a great option. I stayed here a few years ago for Memorial Day weekend. We were kid free, but there were ton of kids there. The lazy river was a nice option. I would definitely stay there again.What about the Tahiti Village Resort & Spa (7200 Las Vegas Blvd South)? Our family stayed there last summer, and it was wonderful! It's a very short drive (or shuttle) to the Strip, but it is excellent for families. It doesn't have a casino on site. It is very close to shopping as well. It has a beautiful pool area, although we didn't manage to try the lazy river.
