Now this I can help you with :) --- too bad TS doesn't have an Orlando section ;). City Walk is a must do!!

It can take days to experience the City Walk, and it's worth every minute. (It's not truly part of the park, so there is no admission to the Walk, only individual covers may apply). During the day, you can shop around the complex, wander around the stores and cafes, catch a movie in their huge theatre. At night, the place transforms into a huge party, with street performers, live music, walk up drink stands. Grab a hurricane at Pat O'Briens, wander around and check out Bob Marley's, Margaritaville, the Latin Quarter (one of the restaurants has a tequila menu). For dance clubs, try The Groove; I think they do theme music nights, when we were there it was 80's music. If you are thinking martinis, try Red Coconut, or the Velvet Lounge at the Hard Rock. And check out the cigar bar at Cigarz.
For dining there's a bunch of choices; there's an Emerils, but make reservations!! The PastaMore has wonderful calamari, but not the best Pasta Puntanesca. Nascar cafe (for the redneck in all of us ;) ) is a great lunch... Basketball fans must check out NBA City. Not only is it the best sports bar (note: Basketball only) I've ever seen, the food is unbelieveable. Wander around the floors and learn the history of NBA (and WNBA), watch Hardwood classic games, and shop your favorite team gear in the NBA Store.
Disney has something similar called Pleasure Island, but in all truth after being at City Walk a few nights, we weren't too impressed by PI and didn't spent much time here. If you do go, please let me know what you think!
