Just want to let you know that baby swap doesn't work as nicely as we thought it would. The examples I have are, Space Mtn, my DH and nephew went on while DD and I waited outside the ride. When they got off I took nephew over to Fast Pass line for babyswap (we had FP and wanted to do babyswap also) they gave us a babyswap card and we had to then enter the fast pass lane. The only plus I see to this is that nephew got to ride twice and he only had one fast pass. On Test Track, we all got in Fast Pass line and went through whole line together (DD included) when we got to head of line we were told to go down to a gate and tell CM by gate we were doing baby swap. We did and he sent us up and down some steps to where people exit ride. We had to wait there for DH and nephew to get done. When they got off we gave DD to them, had to go back to chained off area and wait for CM to let us in. Once in we had to take the stairs back to where we exited when they got on ride. The CM then opened a different chain and we had to get back in line behind the people who just exited from the movie portion. We had thought that at least we would have been able to get on the next car in line, but were told, it doesn't work that way and we had to stand in line again. Granted it was a small portion of the line, but we would have had shorter wait just going in single rider line. Needless to say, another group also doing the swap at the same time we did, was not happy at all. It is a nice option, but just not a nice as it could be.
