Since no one else seems to want to take a crack at this, I will tell you that on all ten or eleven day cruises I've taken in the past, (it's been several years) there have been three formal nights. I'd wager that you'll find this to be accurate. In any case, three should be the maximum, so pack accordingly.
Have a great time,
Will be on the Brilliance 12/12, 11 day. I called RCCL and they told me there were 2. I had asked this question before on this board and I was told that there will be 3. Plan on packing an extra formal out fit just to be on the safe side.
Caribbean Princes, Southern 12/08
Golden Princess, Alaska 5/07
RCCL Mariner of the Seas, Western 2/07
RCCL Brilliance of the Seas, Panama 12/05
Carnival Valor, Western 1/05
Married on Carnival Destiny, Southern 12/2000
Carnival Fantasy, Bahamas 11/97
Hi: It's me again. You may very well be accurate with 2 formal nights. Things are getting more and more "relaxed" on cruises, and it's possible that they have decided to hold the line at 2. I agree that you should probably be safe, however, and plan on 3. (If you're like the lovely Mrs. Jones, you'll overpack anyway!!). Have a great cruise. Wish we could join you!
Unless they are different than other cruise line there will be 3 on a 10 day cruise and we are going on Holland next month and they have 3.Also most of the time you will have them spread out with the formal nites being those days at sea unless they are 2 days together.
