We stayed at WL for our January trip and LOVED it. The grounds are lovely, as is the lobby. I loved the little touches (I'd love to be able to find the Mickey and friends character silhouette coat hooks for the family cottage!) in the rooms and in the lobby. We used the spa pools one night, and they were fantastic after a day in the parks (well, and a half marathon earlier in the day). We only ate at Roaring Forks once (and it was lunch) and found the selection to be adequate and the food to be reasonably good. The best part? We felt entirely at home there.
We found transportation to be the best of anywhere we've stayed. Never waited more than 10 minutes for a boat (and that was at 11:00 at night coming back from dinner at CR) or 5-10 minutes for a bus. Maybe we were just lucky, but they seemed to be really on the ball. We loved the boat transportation and found it to be the perfect end to a fantastic day.
We did find the resort to be isolated, but in the best possible way. The resort just feels so peaceful in the evenings, that it's easy to forget that you're in one of the busiest vacation destinations in the world, and just relax with the lake and the trees. I know that it isn't for everyone, but we really enjoyed the peace and quiet amongst all the Disney craziness.
Have a great trip! I'm sure that you'll really enjoy WL! Just make sure you take some time off from the parks to enjoy the resort! If you do have some time, Fort Wilderness is an easy 20 minute walk along a forested path (you can also rent bikes and head up there) and it's also a lot of fun to explore for an afternoon!
I'm rather jealous, though.
We're getting married this summer and, because of the costs associated with that, our 2010 marathon weekend trip will be at ASMovies. I love the All-Stars, as well, but it's definitely a different kind of Disney vacation.
