I workout everyday even while on vacation. My day is not complete without a sweat session. I know, call me weird but that's me.
The Cosmo gym is one of the nicest places to burn off the calories and build muscle. So many different machines to choose from when it comes to cardio and weight training. They even have a boxing ring. Crazy, right??
The gym is located on the 14th floor next to the salon. Check in at the front, sign a waiver and make sure to grab a towel. There is fresh fruit to grab as you walk out.
I would give it 5 stars BUT when I came in during my last trip a few of the machines were "out of order". Also, the gym is big but needs to be expanded to accommodate everyone. Sometimes there is a wait depending on how busy it is. Nobody wants to wait while on vacation every minute is valuable.
Misc. info: there is a fee to use daily even if you are staying at the hotel. Ask to have it waived (it never hurts to ask).
Daily hours are 5AM to 8PM.
