Excursions in Naples
Being able to plan a group before you sail to maximize your experience and/or save money is one of the reasons we created MeetOnCruise. I'm thrilled that you are using it in this way. Even better, you can actually join the cruise here http://meetoncruise.com/join/NorwegianJade/August082010 and you will be able to see who else is on your cruise and interact with them more directly.
Sounds like a great trip. Enjoy and when you get back let us know how it went.
