Its a shame to try to rush round in a day - you`d miss so much - but if thats all you have...
Bear in mind DL park is roughly 1/4 - 1/3 bigger than WDW`s MK - wear good footwear! And you may not get it all in depending on the opening hours this time of year. If you must try it, save the studios until last - chances are many guests will have done most of it by late afternoon, but if you want to catch Moteurs.. Action check performance times before you leave it too late! I`d also Fastpass SM:M2 asap since its sure to be popular.
If you are familiar with WDW/DLC`s Star Tours and Honey, I shrunk you could skip them - they are identical apart from principle language. Peter Pans Flight is well worth it, but only with a Fastpass, and it can be popular.
Whatever you do, don`t miss Phantom Manor, Big Thundermountain, Pirates of the Caribbean, Its a Small World or Space Mountain - these version knock the socks off their US equivilants. Indy Jones is great (more so now its forward - especially at dusk or night) and Snow White and Pinnochio are great fun, as is Casey Jr.
At the studios, don`t miss Rock n Rollercoaster (can YOU tell its the same layout as Florida?) Armaggeddon or Cinemagique. Catch Moteurs Action if you can and Animagique. The tram tour is not bad, neither is Animation. Don`t worry too much about the production tour if you are short on time.
