Pool hopping. We do it every trip, multiple times. Last week we swam at the Poly, CR, and CSR while staying at OKW. We even went over to SAB around 7pm and walked right in. DS and nephews swam with about 6 other people.
Free internet every visit.
Sometimes shopping discounts when different/better than the AP discount
Occasionally a dining discount at a place that's not covered by TIW
Free internet will be a must have on our next trip. Going for several days on our next trip, and online coursework for classes will still be completed and turned in on time!
