Prepeare to be in familiar, but new surroundings. Walking off the hub and seeing BTM straight ahead is one, and PM being where the JC should be is another.
Fireworks - only in summer season; 4th July thru end of August. Same for Fantillusion. If you are able to, aim for this time to visit for these reasons, the weather and long park hours. Crowds will be heavy but hey.
Attractions - do not miss Phantom Manor, Big Thunder, Pirates, small world, Buzz or Space Mountain in DLP. Do not miss RnRC, Armageddon, Cinemagique, ToT or Crush's Coaster is WDSP.
Try your best not to miss the Fantasyland dark rides (Peter Pan especially - very popular) or Temple of Peril is DLP, or Animagique in the studios.
Star Tours and HISTA are identical to WDW, with Star Tours in french and HISTA having english dialogue in headphones. Adventure Isle, the Treehouse and Storybookland are fun if you have time. Same for the Labrynth. Note - try Casey Jr for fun - the prototype Soundtracker audio system is still used. Animation at WDSP is okay if you have time, Stitch Encounter is Turtle Talk, and the backstage tram is okay with an almost identical Cat Canyon, and am interesting Reign of Fire set.
Eats... fast food is very good. For formal I`d say Blue Lagoon (in PotC) is not that good food wise but for ambience you can`t beat it. Walts on MSUSA is a better bet for sit downs.
