Lisa, I'm curious, what are S-class and R-class ships?
We're booked on a 30 day HAL cruise this January and I'd like one week fixed seating, changing each week. That way we'd meet a good variety of people and still look forward to meeting a new set the second week. Bet that's too much flexibility to request.
We tired of our four table mates on a 14 day cruise -- and they probably tired of us too. We exhausted most neutral topics of conversation and were ready for a switch after the first week. Does that make us shallow conversationalists in 'deep waters'?
