If I could have a free 10-night trip, I would probably split it up a bit. I think I would do 3 nights at a 1 bedroom Beach Club Villa, 2 nights at AKL Concierge, and 5 nights Poly lagoon view concierge with a balcony.
We usually stay at the Poly or an Epcot resort, but we don't pay for concierge. The reason I picked these resorts is because I wanted to be in the Epcot area for part of the trip, the MK area for part of it, and I want to do AKL concierge so I can do the Sunrise Safari.
