Greetings fellow Mouse Fans!
Communication is the key to planning any great trip. But how can you communicate when your family may be far flung? I am a firm believer in the power of group e-mails. You have the cc function for a reason – use it! Keeping everyone in the loop when making decisions ensures that everyone gets at least some of their needs met. Other great options include conference calls or even a newsletter from the appointed "planner."
If your family is local "Disney Dinners" can be a great way to combine a family meal with a planning session. With my in laws, we had a cook out at their house one night and all sat out on the back deck, PassPorters in hand, hashing out the details of our itinerary and dining plans.
Be well and make magic wherever you go!
