i am not sure, but this morning i finally was able to get the 4 night in dec. for my family of 4 since it was available and it had not been available for 4 people since a while ago. before i booked the cruise i saved it to the my saved cruises so i could find out when the lastest we could board the ship, we found great airfare and dh wanted to book , but the day we arrive is the date the 4 day cruise leaves and just awhile ago i went back to look at it again and check what level the cabin was on and to book it, well when i clicked on to book it the next page came up, like i was making a new ressies and of course the cabin is gone. so, if i were you i would not wait and just book the ressies, i believe you have time to cancel before the cancelation date without losing any of your deposit. i wish i did.
