Formal Nights on Liberty of the Seas

Can anyone tell us what are the formal nights on a RCCL 7-night cruise. We are sailing on the Liberty of the Seas from Barcelona on June 18, 2011. On a previous cruise (not RCCL) it was the third and sixth night if I remember correctly. We are just trying to plan ahead a bit.

Thanks for the help.

The 1st will be night 2. The last could be night 5 or 6....it will tell you in your compass!

Thank you for the info. We knew we would find out after getting on the ship. We were trying to find out before as we are trying to make shore excursion arrangements and my time dinner reservations from home. Would like to plan in some extra time on those evenings for getting into our formal attire. We don't want to get back to the ship from a tiring day and have 15 minutes to get ready for dinner.
