For hotels I agree it is hard to come up with a good thread because the topic is so diverse. Mary Jo's sticky thread at the top of the forum is probably the best.
Major decisions that will influence you are: off-site vs. on-site. Walking distance vs. non-walking distance. Hotel shuttle vs. ART vs. self-drive. 2 star, 3 star, 4 star or 5 star?
Everyone - and I mean everyone - here will have a different opinion because everyone weighs things differently.
Overriding things that WDW vets especially need to get a grasp of are:
1. Hotel Distance - Do not allow your comfortable feeling about long commutes to the parks and shuttles and buses, etc., at WDW to lead you to decide you can stay far away from DLR and it will be OK. The walking distance hotels are one of DLR's biggest strengths over WDW and offer huge, huge advantages to your park touring and overall experience. Think about having your hotel room door be as close to the DLR park gates as some of the bus/tram/boat/monorail stops are at WDW to the park gates there. Really.
2. Off-Site vs. On-site - The Disney hotels at DLR are fun but do not offer the advantages that they do at WDW. It is totally OK to stay off-site. You will find many DLR/WDW guests here like me who stay osnite at WDW but always or often saty off-site atDLR.
