If we had a block of rooms, we could probably get a meeting room at the motel and order pizza.  We did this for a wedding a few years ago and it worked well.  Some motel have rooms they use for their free breakfast and those rooms are always empty in the evenings.  Whether we could drink beer in those rooms would have to be checked out.  Some motels have fairly large areas next to their pools. One downside of being next to a pool is that it can be noisy.  Anyway that is my basic thought.
