I called this morning and got an August week for 2010.
Depending on what check in day you want, there are different quantities of weeks available. The order is:
1. 1st person at the door
2. 1st person who calls
3. 1st letter or fax
and so on.
SO, if you faxed in a request and the day you wanted only has two weeks available, you'd be out of luck.
On the other hand, if you're flexible, and are willing to take one of a few check in days, and call exactly at 8, you should be fine.
Reminder, you can't get a FRI or SAT check in if you want to use it for exchanging.
