Been cruising solo for years and love it! Agree that dining can be troublesome if you don't care to eat by yourself. Some ships/maitre d's have done a terrific job of seating solos together, others haven't seemed to bother. Speak with the dining room representative on embarkation day and see if you can get a feel for the makeup of your table. If it's mostly families, see if there is an option to change. When in doubt, I'm always happy by myself with a book at the buffet.
