We've traveled a couple of times with our 19 yo special needs/non-verbal son since Disney began the new GAC process. We traveled under the older system as well, and I've yet to figure out how to get the most for my son out of the newer process. Question 1: Since it is a spur of the moment trip (10/30 thru 12/3) is it better to just have the cast members do his FastPass selections when we go by guest services? The rides/experiences I can do a FP for now are not those we don't necessarily need a FP for. Question 2: Here is my understanding of the process. I can only have 3 FPs at one time and only in one park (just like FP for everyone else). If we used a fast pass, we can go to the kiosk at another attraction and get a return time--which turns out to be the current waiting time to ride the ride. Question 3: Do you all have any other suggestions as to how best use our limited time in the park? This system has us doing a lot of running back and forth, as most of our son's favorites are not necessarily close to one another. If he had his way, we'd park hop all day long, doing his two favorites at each park...lol. Question 4: This trip is to celebrate my husband's 50th birthday....and I've planned it in like 10 days...his entire family is joining us....so far, we've kept it a SURPRISE!! My husband has early onset Parkinson's Disease. His mobility is good, but he tires easily and standing is really hard on his joints. Would he qualify for a GAC as well? I'm thinking we could have 12 of us together if he had a pass as well. Also, are there things Disney does for bdays that I may not know about....I know about the button and we're all doing matching shirts that day. If there are secrets I'm not aware of, please share! Thanks, y'all!!!!
