Yes, you can go ahead and get your wristbands.. You get them at a Kiosk when you walk over and enter The Atlantis. I hear that many people do not ever even use their room, as they are too busy enjoying Atlantis to walk back over to the Comfort.
If you want to look for special rates... We have found that if you proceed as if you are booking the room at Placestostay.com, it will show you promotional rates that are not otherwise advertised or offered. Then, I would recommend calling the Comfort's 1-800 number directly and booking directly thru them. We called and requested the LGOLD rate, and booked our room $134.50. Otherwise, at the Comfort Suites site, they offer an internet users rate which would be cheaper than the standard rate.
