Trip advise: Wash DC, Philly, NYC, Pittsb, Boston in Theme Parks, Roller Coasters, & Donkeys! Posted October 22, 2009 Just a couple of ideas... I think you can travel to Philadelphia directly from Great Adventure without an extra hotel stay. It's probably only an hour or so trip. You can get there by midnight. If you're planning on visiting Niagara Falls, I don't know if you plan on visiting the Canadian side (IIRC, the views are better over there), but if you do, check on the requirements for re-entry to the US on a tourist visa. If there's a hassle or delay, there goes your schedule. Another idea for hiking and nature travel is to visit Presque Isle in Erie PA. It's very close to I-90, actually right next to Waldameer Park. When you're in Shenandoah Natl Park, you should check out Skyland. They have different types of lodging there, from cabins to a hotel, and it's all right in the park. Not sure what you're budgeting for lodging. The Appalachian Trail also runs through the park, so there are plenty of places to hike. I'm also wondering if you might want to flip Kings' Dominion and Busch, so you won't have as far to travel to Charlottesville that night. Just a suggestion.
