Any other choices?
If the Bellagio was "not much more", then that would be worth it - it blows all the others away (have stayed in Bellagio, Luxor and Vennettian and have been around most of the hotel in Las Vegas). Next time we go back (although have no plans at the moment), would either stay at the Bellagio or the Wynn (was still being built last time I was there - Summer 2004 - but is supposed to be fabulous).
The Luxor is getting quite old now, quite dated and a bit on the more "tacky" side of things. I like visiting there (it is quite unique!), but wouldn't choose to stay there again.
Haven't stayed at NYNY. It is a must to go and visit, but I find the theming a bit dark and claustraphobic: very clever, but wouldn't like to stay there (haven't seen the rooms).
Don't know much about Treasure Island.
Go to the hotels' websites and see which one yoou like the rooms and theming of most (I would expect them all to have virtual tours).
