We have some people in our group who want to go to Park A with us in the morning and then go to Park B in the afternoon. Every other day we will all be going to one park a day, and not park hopping. Can we just buy an extra day's ticket for them to use for that afternoon. We do not plan to get park hoppers because we have small kids in the group and I don't think we would benefit for them. However, if someone can use two tickets in one day so they can see two separate parks, this would be cheaper than them buying the park hopper. Is this possible?
