yes, DTD is great and definetely worth spening an evening or afternoon there. Food is great - Gotta try Earl of Sandwich. Delicious hot sandwiches made with fresh cooked meats only $4.95. Great salads and desserts too. If you're a chocolate, ice cream or coffee lover then Ghiradelli is a must. Lots of different sundaes and coffee drinks. Wonderful relaxing seating by the lake. Nice variety of full service restaurants too, all the menus are posted so you can find just about anything you're in the mood for.
Fabulous shopping and some unique Disney and well as non Disney shops. Basin is a store with wonderful and unique (not your typical bath & body works) products. Really nice swimwear and summer clothes shop. They also have Disney Tails which is a Disney pet accessories store where you can get ears and mickey tshirts for your pets. A Disney christmas store and home stores and a kitchen store that has everything disney for your kitchen plus some great gourmet food and wine. Not to mention Pleasure island.
Dont' miss Downtown Disney, it's an essential part of the total WDW experience.
