I was reviewing the point charts (a favorite past-time of mine) and have some questions about the various room categories listed for Disney Collection Hotels. Hopefully some of you have tried them and know the answers. First, what does the Concierge level mean in practical terms at GF, Poly, BC/YC and AKL? Second, what is the difference between the many room categories listed for the AKL? The choices are Water/pool, Savannah, Deluxe water/pool, Deluxe Savannah and Concierge. What do the "Deluxe" versions of the water/pool or savannah mean? Thanks for any insight or experiences you can relate.
