The Taj Mahal is very nice. I stayed there about 2 years ago. They also recently put up a new tower and the rooms there (Chairman tower rooms) are supposed to be amazing.You might also want to check out Caesar s. They opened up a new club (Dusk) a few months ago.
there are quite a few sites that you can search that will likely show you great hotels at the best prices available. check out the website BookMe and you will be able to compare prices on all the reputable travel sites in just a couple minutes. it s very convenient and will save you a bunch of time and money. Also, make sure you buy them online... otherwise they charge much higher fees for phone orders. good luck.
