My husband and I have a quad at the Wyndham from Thursday night through Sunday (checkout). Our original roomies bailed on us, so we now have two spots. We may have found one other person (a guy), but that hasn't been confirmed. Anyway, as of now, there's room for you if you want it. We and the possible third roomie are about your age. We're quiet in the hotel, and it sounds like you're also interested in a calm environment.
The room is in my name, and I'll be arriving late Thursday night (around midnight, I suppose), so you wouldn't be able to check in until then. If that's OK with you, let me know so we can coordinate plans.
