I want to take my 13 year old grandson to Washington DC starting trip June23. He has mild CP and can walk with a walker and uses a wheelchair for visiting big area sites. We are driving and want to see historical sites representing founding of United States. It will be his course of study for 8th in California. Does anyone have any ideas for ways to go to see the best sites? I am a teacher and we are on a budget but will be using motels and eating out. Ending our trip is optional. I would appreciate recommendations for clean hotels and places to eat. Thank you grandmapeaches
