We are going for 6 nights in October with a family group. One person handled all the reservations. She has park hopper passes for us. I think there is only 1 or two days that we need to go to two different parks in a day. I just priced it by purchasing a 7 day pass and it was $200 cheaper. Can you do that? Use another day on a different park after you spent the morning another park? Thanks!
