My advice, read through HydroGuy's superthread, it is amazingly useful and will answer many of your questions. There is very wide consensus here in the DLR forum that his is the very first thing to read about DLR for WDW vets, and it will get you up to speed about DLR (layout, differences, similarities, hotels, etc.) pretty quickly. Then head back here into this thread and ask your fill-in/follow-up questions. Also, welcome!!!
