I talked to a guy on our last Princess cruise who wasn't going to do formal night any more on any cruise.He didn't feel like packing the formalwear,plus didn't want to pay the cost of renting a tux.He was just going to head up to the Horizon Buffet and relax.
What I saw of formal nights were most men in suits and ladies in nice dresses. Not too many gowns like the cruises before. Some men had sports coats on, I would think that it isn't tha formal anymore but men do have to have a jacket on. The buffet is always an option if one doesn't want to get dressed up. After all its your vacation so do it your way. Have a great cruise!!
I have been on Royal Caribbean cruises the past 3 years. My first cruise, I wore a tux. The second one, I wore a suit. The third one, I dragged along a sportcoat and went in that both formal nights. No tie. Noone said a thing, and they won't. It's your vacation; dressing formally is NOT a requirement to eat in the dining room; at least that was my experience on Royal Caribbean.
Going this year on GOlden Princess, debating whether to even take a sportcoat this year.
Oddly enough, I have had the opposite experience. The first few cruises we took, I was in a sport coat at dinner, then for the last few, a suit. For the next two cruises, I have purchased a tuxedo. I like the way the men look in a tux, and I thought it was time I joined the crowd.

We are just off the Caribbean and most men wore a dark suit. Even my 14 year old wore his suit. We had family pictures made and everyone looked very nice and mom is happy. (Except for the fact that she is home and off to work tomorrow!) Most women had on short dresses. My 18 year old girls wore prom dresses to get another night out of them. On the Caribbean the Caribi Court was the best buffet for dinner. Also late night snacks per my 14 year old son!
