Not really, my wife has MS as well as a variety of other issues that limit our daily park time as she is completely worn out by 4:00 in the afternoon on most days. I applaud the Disney CM for seeing a need and taking care of it the way they did. With six/seven hours of park time available to us, with the 3 FP+ limitation we were unable to do a few of attractions even with a 14 day stay. We picked and choosed our daily rides and were given return times for the ones with non-accessible lines which negated the need for many if not all FP at SM, SpM, BTMRR, and a few others.
Something that has not been noted yet about FP+ is that even if you have a FP+ reservation if you require wheelchair accessibily you can still be denied access to the show/attraction. We were twice denied access (BatB and Fantasmic) during Christmas vacation much to our dismay, neither time were we offered any replacement FP+ at the parks.
