Las Vegas is one of those cities like Bangkok where everyone under the sun has a hotel suggestion, and they're all valid mind you
I have stayed at the MGM Grand and I wasn't a fan of the rooms or the location - you see, I don't like walking at all
- that said, the pool party is amazing - if that's your kind of thing, like it is mine
The Bellagio:- stayed there, rooms way too old for my liking though. Nice pool area.
Planet Hollywood:- much younger in appeal, nicer modern rooms, lots of college students though, but the rooms have the best view of The Strip in my opinion. Why? Get a Premium Lakeview Room with the view of The Bellagio Fountains almost directly in front and with the Eiffel Tower adjacent, up close and personal, to your right.
Paris Las Vegas:- outdated rooms, small pool area, but tanning under the Eiffel Tower - a fun gimmicky thing to do
However I would suggest looking at the Vdara and that will be my likely abode for 10 nights next July. Near new property at Center Strip. Couldn't go wrong with that choice.
