Has anyone ever upgraded there Play 4 Days pass to a Florida Resident Seasonal Passes after using up all days on the pass? I am planning on using all 4 days on my Play 4 Days next week and I am going back at the end of May. I wanted to know if they would allow me to credit the full price of the Play 4 Days pass towards a Florida Resident Seasonal Pass and let me pay the difference when I go in May.
