Here's a great article from the Boston Globe about traveling with your family. 

All Inclusive:  "A family trip involving several generations can lead to precious memories - if you can organize one without killing your relatives first. Here are some pointers from a pro".

The article highlights ways to keep trips running smoothly for kids, parents and grandparents alike.  How to choose your destination, how to make group decisions, and how to keep the peace.  Apparently more and more families are traveling together for either destination reunions or just fun family trips together.

This is a good read - especially if you are considering an upcoming trip with your extended family.
