We did 3 room/resort switches on our last trip and I think I used it 2 out of 3 times...it was pretty slick at Vero but I can't see that it made much difference one way or the other at any of our resorts, things went pretty fast regardless. And we did generally get our room requests. So, whether I do it or not in the future will mostly depend on whether I get the time to and think of it or not! I think I would do it if we were planning on checking in at a "busy" time but as long as we avoid the Friday before Marathon Weekend or the like I wouldn't worry about it. (We did have one negative experience in the past with checking in at the Pop Century on Marathon Weekend once and, never again!)
