I wish you well in whatever you decide. Each person gets value out of different things. We've never stayed at any of the 3 DLR hotels so I can't speak from personal experience. I don't get the "magic" of walking through Downtown Disney that some refer to, I but respect that they feel it; for me once I'm past the World of Disney I don't feel any Disney at all between there and the hotels. We do enjoy walking around the DLH sometimes when we are there. We enjoy the ambiance for free (of course, we can't use the pool) and then leave.

We also enjoy walking into the GCH and looking around for a bit for free and then leaving. Our ideal target is $100-$120 per night (including taxes) and we almost always get that within walking distance on Harbor. So in terms of hotel cost we can do 3-4 trips instead of just 1. We spend most of our time in the park and I'd rather relax on Main Street, the back of Flo's, in Critter Country, etc than in a hotel room. All that said, if I could find the DLH for under $200/night sometime I'd definitely stay there for the experience to actually see for myself. Maybe after that I'd be hooked and not be able to go back to Harbor.
Good luck on finding at rate at which you get value from your stay! I'm sure it will be wonderful!
