I am sure you will be just fine

.
Last summer, we purchased one annual pass and two "weekday" passes for Aquatica, the latter of which were only listed on the FL residents section of the website. We are not residents of Florida, nor even of the USA....so I was a bit concerned about whether we could buy and use them or not. I called SW before purchasing to see if we might have issues when we go to enter the park. They assured me that the weekday passes, while listed under the FL residents section of the website, are open for purchase to anyone (they are marked to FL residents as they are the largest sector of consumers to purchase that type of pass, hence being placed in that area of the website). They even put through the ticket purchase for me by phone using my Canadian MasterCard.
When we entered the park with our ticket confirmations, we had no problem at all.
