During the long Labor Day weekend, there's a chance that the lounge will be completely closed. You need to check with the hotel since the lounge is important to you. [Globs get free restaurant (buffet) breakfast when this happens, and often free drinks or appetizers too, but I don't know what would happen if you were using one of the Explorist Club Access Certs, including if the lounge is open for only part of your stay.]
