I stayed at the mandalay bay during the week & had an alright time there.
I don't understand how this pool ever gets rated #1 in las vegas. the music was terrible, you had to fight to get seats, and the lazy river was not that impressive. The wave pool was were it was at. plenty of room , while every other pool was crowded and filled with little kids.
the rooms were fabulous, nice size, great bathrooms and also comfy beds. The casino is alright, didn't really like their slot machines but craps tables were good.
the place was nice and clean but so far away from the strip so you had to take a taxi everywhere which gets expensive, yes there is a tram but it only goes 2 hotels down :(
