Hi Susan! My husband and I also enjoy the formal nights. Guess what! I bought a formal gown marked down from $136 to $21! It's gorgeous.
In November, we are taking our 3 grown children and their spouses on an 8 day cruise. The girls have had a blast looking for gowns and have gotten beautiful dresses. We are renting tuxes from the ship. That is what we have done for our last 3 cruises. Since we plan to continue cruising, and love the elegance of formal night, I think we will start looking for a tux for my husband. The only thing is, it is so convenient to have it delivered to your cabin and not have to pack dress shoes, ties, etc. Guess I'm basically lazy!
I do hope they never take away formal nights. They are so romantic and beautiful!
