Busch Gardens pass help...?

[This Girl]

I used to have a Busch Gardens 1 year pass, and I still have that one, but now it's expired. If I'm planning to go today, does anybody know what I should do? My mom's out of town, so she can't come with me. I have a school ID, which she told me to bring if I go, so that they know I live in the area. Would I have to have them call my mom to get info for a new pass, or would I have to get information from the website, or what? Please help, thank you
