We are traveling for 14 days and are looking to see Gettysburg, George Washington's Mount Vernon, Washington DC, Frederick MD, Harpers Ferry National Park, Antietam National Battlefield, Great Falls National Park, Possible Fredericksburg VA, then Driving through New York up the coast to Rhode Island, stopping in Boston MA, then Driving to Niagara Falls, Stopping at Rock and Roll Hall of Fame on the way back home. Here are my questions for this trip: How many days should we spend in Gettysburg 1, 2 or 3 , we were thinking of getting a licensed Battlefield Guide, do you recommend a guide and if so there is 2, 3, 4 hours you can get, is there a benefit to a longer tour? I have read on the forum that Fredericksburg VA may want to be avoided, is this true? Is Valley Forge National Park worth making the trip to see. We would like to see Hershey Park if we have enough time but it is not a necessity. For Niagara Falls, it is really worth the extra money to get a room with a view of the falls? it seems like there are a lot of extra charges for rooms in Niagara Falls ON, is it better to stay on the US side, can you walk across the bridge from US side or better to drive? And last but not least is the Amish Heritage Trail in Indiana worth seeing all the floral quilts and quaint towns? I know that there a lot of questions in this post but we have never been to the East Coast and are unsure of traffic and using the Metra in Boston and DC. I assume that the parking arrangements at the metra stations are fairly safe... I hope. Any advise you may have for us would be great. We are traveling in September. Thanks in Advance.
