Q: Can anyone tell me how many formal nights there will be on the 12 night Carnival Splendor Baltic cruise-and are they properly formal-i.e tux and bow-tie?I've never been on a Carnival cruise and they have the reputation for being "fun" rather than formal so I wonder if people actually dress up like they do on princess cruises, or just go casual all the time.I would be grateful if someone would put my mind at rest!Thanks
