One word...AMAZING! My good girlfriend and I just stayed at the Cosmopolitan (Thursday-Saturday) and LOVED it! I highly recommend this hotel! Everything about it is beautiful, the staff is amazing and we felt extremely comfortable and safe at the hotel. We truly felt that the management kept an "eye on things" that were going on in the hotel. We loved the hotel bar near the slot machines...are bartenders Trey and C.J. were awesome and we went back every night :) :) :)
This hotel is classy and it is worth the extra money. I dont gamble (but I still love Vegas) but even I enjoyed their casino!! They have three pools (which werent open when we went, but were gorgeous), several shops and restaurants to choose from.
Also...there is an awesome pizza place thats open until 5am...only $4.50 for a HUGE slice!!!
Definately splurge and stay here! We willl only stay at the Cosmopolitan from now on when visiting Vegas!!!
