They are the same size as the regular rooms but have two robes for use. There is a lounge with sodas, water, coffee, and tea available all day. There are light breakfast offerings, late afternoon snacks, beer/wine from 5-7ish, and late evening desserts around 8. If you make good use of the lounge food it might be worth it, but otherwise, no differences. You also have to use your room key in the elevator to access the club floor.
