Jeanine....my husband is sometimes a loaner and other times a loner...and then again sometimes the life of the party. When Tom doesn't want to do something, he generally won't and I go off on my own - my friends have joked that we need loaners for those occasions.
I think both of you will be very comfortable on Radisson - there is no forced conviviality - you can do "couple" things or "group" things. That's what makes it such a great cruise line. So, take heart, come ahead, you'll love it!
