Jumping in with another question...our youngest is just under 42", so there will be several things he can't ride. There are only a few of those that all of the rest of us will ride (you won't see me on ToT or RnRC, lol) so right now I have fast passes for all 9 of us for Space Mountain, for instance, that the little guy can't ride. So from the rider swap discussions I'm seeing today, it would appear that I could change my (or DH's) and the little guy's FP+ to a nearby ride at the same time, go with the group to Space Mountain so the one adult can get a rider swap, and then take the little guy to the other FP+ attraction. Then the other adult goes to Space Mountain later. My question--is that scenario frowned upon or "gaming the system", since that effectually means the 2nd adult gets an extra FP+, or it is generally acceptable to take the too-short child to do another attraction that also requires FP+ rather than sitting around waiting? That option hadn't occurred to me before reading the 2 rider swap threads going on today--we were just going to wait it out.
