We did at the 9 month mark and I still feel that was a bit too early. Some people are saying the longer you wait the cheaper the flights get I sappose that I didn't want to take the risk of the resort being booked tho. I guess the good thing is that I booked with all people I really really want to be there and then I any other amity o friends want to wait and book closer to the ate they can still do so just not be able to fly with us as a group.
