Visby, Sweden

I've never been, but Rick has a section on Visby in his Scandinavia book (since you're on a cruise, you will be seeing lots of other places covered by this book, so it will be very useful). Here's the Visby port review on Cruise Critic. Note their opening sentence, "To be honest, there's not a great deal to do in Visby. But then, that's kind of the point of the place." http://www.cruisecritic.com/ports/newport.cfm?ID=477
