I go every Feb. usually just for a long weekend. This time I booked a whole week. I had a 5 night comped trip for any Harrahs property inc. $400 and 150,000 credits. I chose Ballys because I was taking my 82 year old mother inlaw. (Ballys is more like the casinos she remembers) I also had a comped 3 night stay at Encore. I overlapped those so I could have some alone time. But I booked our last two nights at Cosmopolitan for fun. Anyway Ballys room is huge and the best bed out of all 3. Gambling was ok at all 3. Don't care for BJ at any Harrahs property(6/5 BJ). Saw Dance With Me at Wynn, well worth it. I liked the King suite at Encore the best. Layout and view was good. But, Cosmo view of the Bellagio fountain and Paris lights is awesome. Cosmo fitness room and pool the best. There is a boxing ring in the fitness room to get your aggresion out after losing at the table. Frankly while at Cosmo, I gambled mostly at ARIA. $10 dollar BJ table with didn't have to double the bet for 2 hands. The poker room at ARIA is awesome, played a couple of tourneys. No Poker room at Cosmo. After 1 week came home only $400 down. Lots of fun.
