We typically sail Azamara, Celebrity in suite class, but running out of itineraries. Have sailed Princess, and Holland America. Princess OK, HA not a fan. We do like the nightly entertainment including shows, singers, dancers and some rock music in the lounge at night, not a fan of jazz or piano bar. Guess we still think we are young even though 70. Looking at an upcoming Seabourn and Regent cruise. I hear the food is very good, but are there other things going on around the ship? Or is the entertainment more socially oriented? Also husband will wear dress shirt and khakis but not a blazer. Seaborne says we would have to eat at specialty restaurant on formal night if he doesn't wear a blazer but cannot guarantee that we can get a reservation for that night. Any opinions? Silverseas said he had to wear a blazer every night for dinner, so unfortunately we ruled Silverseas out. Has anyone been on Silverseas and can verify mandatory blazer? I find that recently cruise lines have been became more lenient with regards to formal dress code. Thanks for your feedback.
