My husband and I are heading to Las Vegas in April. We always stay at either the Venetian or the Bellagio, but this time we decided to stay at the Cosmo. I got a great rate, but after reading the reviews on TA I am really worried and am considering changing. Is it really that bad? People are saying the service is awful, the hotel stinks, the rooms are very small. Yikes! Have I made a huge mistake? I also hear it is a hotel for mostly 20 year olds. Is that true? We are in our fifties, but young fifties, not old geezers! Need some advice!
