I've been given permission to leave my car in a motel parking lot when I've taken off on short tours. I usually stay at the hotel for at least one night of my tour (usually first or last), and I always ask permission (at least partially so no one thinks that car is abandoned, don't want it to be towed!). I've had pretty good luck with that.

You might try calling the Belfast Chamber of Commerce and asking if they have any suggestions.
