Thanks, Sonnyjane and hootey! I'll talk it over with my husband in a couple of months. We have gone to WDW for the last two years (and again this year) and we stay onsite at some of the Deluxe hotels, so we definitely know Disney isn't cheap when it comes to their nicer hotels! We'll be staying in cheaper motels/hotels the rest of the trip, so we might be able to swing the GC since this might be a one-time trip, but we'll stay open to non-Disney motels as well.
The only wrench that could be thrown into the plan: As of now, we won't be going to WDW next year, so the money we usually spend there will go toward this trip. However, I've got a deal with him that when I lose 50 pounds, he takes me to WDW for the Christmas festivities - the one time of year that is hardest for him to get away from work, but it's #1 on my Bucket List to see the Christmas decorations and go to
MVMCP.
Since I know how that sounds, it should be noted, this was completely my idea all the way around (DH told me not to lose any weight, but it's for my own health and happiness) but he also agreed to that plan. I've been rewarding myself with every 5 pounds I've lost (little things) so that would be the ultimate reward

(not to mention motivation!!).
I told him it's entirely possible that I'll reach my goal by next year (14 pounds lost since Christmas), so we might be going for Christmas 2013 - which means a trip to DLR in May and WDW in late November/early December - if we do that, it will be an Adults Only trip and I requested to stay at the Grand Floridian (a place I've always wanted to stay, but with kids, the Contemporary is the best fit for us because of the walkway to MK).
If the GF is definitely in the cards for us, the GC might have to fall by the wayside since both "Grand" hotels would cost us an arm and a leg visiting them within months of each other
