They may surprise you. Cruises offer so much these days, I'm sure they will quickly find many things to their liking, and you may see less of them than you think! Treasure this opportunity. I have fond memories of taking my father on a cruise, and each cruise since I've sat on the balcony at night, watched the stars, and wished I could take him with me on a cruise again. I have to believe he's up there in those stars "with me" each time.
