Do all rides have this? How does it work? We are hoping to go this weekend and have a 3 year old and an 8 month old. Any tips? I just hope the weather improves!!!
Most of the attractions that are restricted allow baby swap - Indiana Jones, California Screamin', Thunder Mountain. I'm not sure if the Matterhorn has it, though. Let the CM know before you go on the ride that you want to do a baby swap. They'll allow one person to go on the ride, and then the next person can go through the exit, without having to wait in line again -- they'll instruct you.
Some rides, like Soaring Over California, might be quicker if you do the single rider line, if it's not long. The single rider line is used to fill in unused seats (party of 4 and there's 5 seats - single rider gets the extra seat) - that might be faster on that attraction -- ask the CM to make sure.
I recommend going to City Hall at Disneyland and ask them if they can give you a list of attractions that offer baby swap.
Have fun! I think the rains are supposed to stop by the weekend.
