Vacation or something

The ‘rents are talking about taking a cruise next year. I really want to go with them and I think we can make the finances work with sufficient time to prepare. However, I’m also having this nagging feeling like I’m overlooking something and this won’t be as much fun as I think it will. We enjoyed our honeymoon cruise and said the only thing we would need to have to do it again would be people we knew and liked to sit with at dinner, which if you go with the family, is pretty much a given (I hope). So, why am I vacillating on this?
Darn brain.
