Cruise/Vacation Ideas Needed

[RobinKY]

Next summer I will be going on a sabbatical for 2 months.  I will have a couple trips planned with kids and one just with SO, which will probably be a Med Cruise.  I will have 4-5 weeks to fill up, although financially I cannot vacation during those entire 4-5 weeks.  Any ideas for cruises or other trips that would just be me?  I prefer not to be off the grid too long (more than a day or two at a time).  I assume I'd be paying for two even tho cruising alone. 

 

Has anyone done a train vacation?  I was looking at a Chicago --> Seattle --> San Fran --> Chicago train trip.  How do they compare to cruises - food, sightseeing, interaction with others?  I know nothing about train vacations.
