Well, despite all the predictions about no other off site resorts,, whether they are accurate or not and I don't wish to pursue that line of discussion (hense the comments) the original question is "If I could choose...' and I would choose another offsite location on this side of the Rocky mountains so that it was within reasonable driving distance. Possibilities?
Texas Coast
Colorado
Washington D.C.
New York
Grand Canyon
Other National Parks
Just my preference. There are plenty of WDW options with the development of SSR.
