I have a friend who works for a limited-service property. I'm not sure what FedRooms is, but I know his property offers gov't rates of $111/night, when rack rates are much higher. One of the things he & I were talking about recently is that often they get someone who books the gov't rate on the weekends for 2-3 rooms (and they know it's really for a softball tournament or something). The property asks for gov't ID & usually the person can provide it & assumes it will cover all rooms, but it does raise the question of how many rooms by a single gov't employee can be booked & if the gov't is ok w/ its rate being used for softball tourneys, especially when rack rates are so much more.
Cheers.
