4. Rider Swap
If you do want to ride one of the “big” rides (i.e. one with a height restriction such as Expedition Everest, Space Mountain, etc…) Disney has a wonderful service called Rider Swap. Just approach the cast member at the ride’s entrance and notify them that you’d like to use rider swap. One adult will then ride while the other adult waits outside with the infant. When the first adult is finished, the second adult uses a sort of Fast Pass ticket to skip a second wait in the line.
