We need a room at a airport Hilton. The rates are all over the place but the mobility/hearing access suite is considerably less then the regular suite using the MVP rate.

Because of our arrival time ( after midnight) and our international flight departure time ( mid afternoon) we probably will be hanging out in this room instead of venturing out into the city which is an hour away by public transportation. So the idea of a suite is attractive.

Are there rules or restrictions regarding reserving mobility/hearing access rooms/suites?

I know mobility access seats on airlines are usually open to all with the caveat that you might be moved if they are needed.
