What my DH forgot to mention the most important thing: the swap meet had the cheapest souvenirs on the island! It also was more "new" items, not the typical flea markets I've been to. If you're looking for Hawaiian shirts, muumuus, magnets, key chains, ukuleles, beach towels, floral bags -it's the place to go! My DS is a key chain fiend and we found booths with the plastic key chains for as little as 12 for $5, then we found a vendor selling two bunches (24) for $9!! He bought enough to give out to his whole class. They also had a lot of fresh fruit and nuts vendors, and artists as well - there were a couple of carvers that were making the most beautiful and intricate designs. Also, post cards as little as 6 for $1 (although I also bought the 10 back at Aulani for $8).
And going back to the pool chair situation, we did have a couple of families that did give up a chair or 2 for us on a couple of days, which was nice.
