We sailed Jan 19 this year on a 4 day and got the Florida Resident rate. Most of January and February were available at the rate. It was a great savings so it became a last minute Christmas gift. As I recall, the rates became avaiable in November. On our cruise coming up this Nov, we booked at regular rates through DU, and they immediately notified us when Florida Resident rates were made available for those dates. We had several rooms affected in different categories. My daughters originally had Cat 11, which were not included in the Fla rates. DU checked on Cat 10, which were included. So they got upgraded to Cat 10 and still saved several 100 $ over the original Cat 11 res. DU was very aggresive in getting the best possible deal for us. I was impressed! By the way, they did tell us that the Fla rates apply as long as at least 1 person in the room qualifies. Doesn't have to be everyone.
