Some of the shops can get into Gulliver's off season, for ice courses, etc. Tri-City has an upcoming underwater tree trimming. But AFAIK, you can't get in for regular diving. Dean's diving has some pool time tomorrow (call the shop for details) and will have more over the winter. Or if you are really desparate, I think you can get in at Innerkip, although personally, I wouldn't dive there.
