Stayed in Atrium suites once about a year ago. Agree with @
Penguin -- they are the amongst worst place I've ever stayed. The worst being a three way tie between Hooters, Fremont Hotel, and Travellodge on Long Island - Hooters for the overflowing toilet, Fremont Hotel for the bedbugs, and Travellodge for the peepholes between rooms and needles in the parking lot.
For the Trop, South Tower is nice/great. North Tower is pretty awful except top floor. The Chelsea is quirky and worth one stay -- especially if you can get the PH room with the fireplace. Havana is close to parking and that's about it.
Super shitty slot service at Trop. Takes forever to get paid. On the good news side, it's the only place I've ever hit a jackpot waiting to get paid on another jackpot.
