The cut-off date for the $100 government rate at the Hyatt and the Comfort Suites is at midnight on June 7, 2012. After that rooms will be based on availability at the prevailing rates.
There are still some rooms available 6/24 - 6/29 at the Comfort Suites. The Hyatt is essentially full (the entire hotel, not just our room block) but you can keep checking as there may be cancellations. Please let me know if you have any questions.
