Of course items will have changed since this video was taken, but it gives you sort of the "flavor" of what's offered.
I don't recall seeing many sweatshirts, more of a large selection of T-shirts and Hawaiian shirts.
The video was taken before they added the newest gift shop, the new gift shop doesnt really have t-shirts though.... it's is more high end "Tommy Bahama" sort of murchandise such as high end sun dresses, sandles, hats and jewelry.
