and maybe ...
(since we just went with someone who fits this)
4) someone who has a sketchy or intermittent disability (autoimmune, joint pain, etc), that gets the GAC "in case", and barely, if ever, uses it. We were there 7 days, and my friend got one "in case". Never used it, since she took breaks at the hotel, sat down and rested, and just didn't go on some rides. She got it to be sure if it got bad enough, she could still be sure her kids hit the rides, but never took advantage of it. This was her 8th trip, and first gac, and still, fp was good enough for the whole trip.
It is good to remember that not everyone automatically takes every advantage when they know it isn't needed.
(of course, if she didn't validly need it, I am sure her moral objections to abusing it would not have been that great)
