We used to not park hop very much, but with Maxpass, we park hop every day. It is so nice to start out in one park then collect fast passes for the other park before switching over. I'd say do both if there is any way possible. I'd even rather do just 4 days if it meant having both PH and Maxpass. If I really had to pick one, I think I'd pick Maxpass. We focus on rides though. I feel like we ride a lot more rides and wait a lot less time with Maxpass. If rides aren't as important, I'd go with the PH tickets because you'll have more flexibility for shows and entertainment.
