I have no idea why they wouldn't have a five days bundle

.
We are going to be staying for five days in June so that would have been perfect for us. What we ended up doing was getting the 4 days of park to park tickets and then just adding a single day of the one park tickets. I figure we'd probably just do the WWoHP on the last day so we wouldn't be going over to Studios.
Anyway, when you do plan it just make sure you try different ways to bundle to compare the best price. We were going to do the 3 days of park to park and two days of single park tickets. But it actually wound up being cheaper to do the 4 days of park to park and 1 day of single park tickets, which was weird but hey I'm not complaining
