My sis and I are in our 50’s , and we love Seabourn. We don’t dress up , nice jeans and a top. The people we met on Seabourn were so much fun. Three cruises with them , and our fave so far. We’ve done Oceania in 2019 , and I got kicked out of the Asian restaurant for wearing jeans maybe ? It’s not more relaxed so I’ve been told. Oceania is 5.5 star, Seabourn is 6, so idk if that helps 😉. Ps we don’t “party”.
