If you had a room reserved at the Hyatt for the March dates, your reservation is being automatically moved to the August dates, and your confirmation number will remain the same. You do not need to call the Hyatt to confirm, they are still in the process of switching all of the reservations over. All rooms at the hotel are being held in the block, there are no rooms available outside of the group block. The Hyatt is aware of the date change and is holding all of the reservations that were already in place.
Many attendees have been calling central reservations and getting mixed messages. Please be assured that the Hyatt is aware of the rescheduled dates and are working diligently to update their systems. We know that there will be some rooms that become available at the Hyatt due to the change, and as rooms become available we will provide a link to registered attendees if they would like to book a room. You do not need to call the Hyatt if you already had a room.
If you previously cancelled your reservation with the Hyatt on your own your reservation will not be reinstated to the new dates.
Some of the overflow hotels are working on the same procedures as the Hyatt. Please allow them the time to change over reservations before confirming with the individual properties early next week.
