Unfortunately, much of the DVC merchandise is quite generic and not resort specific. Several limited edition DVC resort-specific t-shirts and mugs were offered on the Disney Store website a few months ago, but now the offerings are general DVC. Surprisingly some resorts, like Animal Kingdom Villas and Beach Club Villas, were not included in the limited time offering. DVC aside, I do not understand why there is not more resort specific merchandise. I, for one, would love to have resort-specific polos and t's.
Regarding my noting Fittings & Fairings, the shop features business casual offerings for its conventioneers. Ralph Lauren, for example, is just one of the brand offerings.
To some extent, gift shops can give an indication of a hotel's/resort's target demographic. A stroll through Fittings & Fairings suggests a business clientele and, specifically, a demographic distinct from the other deluxe resorts.
