Of the ones we've stayed at, CSR is our fav- that's why we chose to stay there twice. We've stayed in Rachos and Cabanas, and it was a bit different each time, but very enjoyable.
We were going to stay again, but thanks to a great discount, are trying AKL! I think that may be the new fav!
We've visited some resorts to eat, but my goal this trip is to visit each resort we've never been to just to check them out. For our family's taste, and if money were no object, I think AKL, WL, and Poly would be our top picks.
That's one thing I love about WDW resorts- there really is something for everyone's taste, touring style, needs, budget, etc.
