You can't beat the view from the lounge and the spaciousness. By comparison, the BC's lounge is much smaller. The Volcano pool is not Stormalong Bay, but it's fun and it's wet. I'm sure that you'll be spending a majority of your time at the MK and getting back and forth with the monorail and boat is very easy. Plus, you're only a short walk to the TTC to pick up the monorail for Epcot. Just keep checking back to see if the dining plan opens up, but I think with the concierge lounge, you'll actually be just fine.
