My FIL had a double knee replacement this winter and up until now has been playing Hercules with our upcoming trip. Today, however, we both finally got real (I am post hip op) and since our trip is so close, I got him to lay out what makes things harder for him. Overall, he has done fantastic in his recovery, but he has a hard time standing for extended periods. He is very worried that this will impact how long he can last for the day. He has no trouble if he stays walking, but when he sits or stands for extended periods, his knees get swollen and he needs to elevate them. We've already discussed getting to parks for Rope Drop and taking midday breaks to minimize wait times and navigating crowds, and DH is a Fastpass pro so I plan on taking advantage of FP by cutting waits down. Also, FIL is walking every day and doing PT to build his endurance for the trip. I guess my questions really are if A) it's worth it to get a GAC and if there is really anything Disney can do to accommodate -- it's not like they can give him a folding chair for the line so he can alternate sitting and standing and B) are there any good places in the parks where he can elevate his knees for a bit if need be? I know First Aid might be able to help but I was wondering if some shows or areas have spots that he could relax in to rest up. Thanks for any advice!
