Onboard shops include:
Mickey's Mates -- Located on Deck 4, this is your cruise line
Disney Store! Disney merchandise of all kinds are available here, including postcards, trading pins, plushes, t-shirts, and logo merchandise of the
Disney Cruise Line and the ESPN Skybox (a pub aboard ship).
Treasure Ketch -- Also on Deck 4, here you can purchase tax-free items such as watches, jewelry, loose stones, film and batteries, books and magazines, and upscale merchandise.
UpBeat -- Here you will find tax- and duty-free fragrances, liquors, and premium cigars; however, you may not consume the liquor you purchase on the ship.
Preludes -- This is the theater snack stop, complete with candy, peanuts, and popcorn.
Shutters Photo Gallery -- Throughout the cruise Disney photographers are ready and willing to snap your photo. You can be photographed with a variety of backgrounds and a variety of Disney characters, too! You'll find your photos each evening on display in Shutters. Purchase them as you go along (and save your receipts for possible quantity discounts) OR, if you'd prefer, review your photos every day. Discard the ones you don't want and stack up the ones you do behind each other. If you don't do this, there's a good chance all the photos will be discarded. Also, don't wait until the last night of the cruise to purchase your photos -- as you might imagine, Shutters gets VERY congested at the end of the cruise. Be sure to keep your eye out for specials in the Personal Navigator. On my last cruise, I was able to get a free 8x10 of the ship and characters because I'd purchased a certain quantity of photos!
As a side note, Disney had many loose gem stones on the ship. If you are interested in citrine, amethyst, blue topaz, sapphire or garnet, the ship offered a large selection at $10 per carat. They even offered pairs for earrings. This is a great price if you want to make your own jewelry.
