Trust me, your vacation preferences change over time. Will you still be going to Disney in 48 years? We still go after 20 years but do fewer park days now that kids are grown and not nearly as often.
I don't like the restrictions with RR which is why we passed on that resort and added on someplace else last summer. It will always be last on my list.
I agree with Rose Gold but I have one question. Have you stayed at all 3? If not, I would before I purchased.
I have stayed at AKL, Boardwalk, Poly, and OKW. AKL has been my favorite so far, though I loved the location of the Dolphin when I stayed there.
