Need help... Please point me in the right direction and offer all the helpful advise you have time for.

The grandparents (about 12 adults in all) are planning a family road trip with the grandchildren ages 2yrs to 12 (about 15 children in all).

We are planning to rent an RV and travel from Boston to Disney, over a two week period; sometime next summer.

We definitely want to do some sightseeing, on the way down and on the way back. Key cities and states that we know of so far are Washington, D.C., Atlanta, and Philedelphia

Note: we are first timers; thanks for any and all direction you can suggest to us.
