How early do ticket centers open?

[engle]

I have a voucher to redeem for an AP. We are doing AK the first day and it opens at 9am. However, I have a resv. for Donald's Breakfastosaurus for 8am. What time will the ticket centers open for me to activate my AP?? If I get there at 7:30am will that give me enough time to activate and will it be open for me to do so? Also, one person in my party will need to buy a 3 day hopper. They can do that at the same place and time right??
