I'd fly into Denver, rent a car, book a motel or cabin in Estes Park and spend a week exploring Rocky Mountain National Park. // We live in St. Louis, not on the East Coast, but FYI my total spending for a week like this last summer for three of us (DH, me, and DS 20) for a seven night/six day trip was $3300 and that includes food, spending, and sending the dog to the Kennel.
There are wonderful family friendly hikes and ranger programs there. If you get up early, you can park at one the popular trailheads. If you get up later we park at the visitor's center and take the hiker's shuttle in. And one day do the drive stopping at all the scenic outlooks on the way to the top of trail ridge road and back. My very favorite hike is Emerald Lake. I also highly recommend the architectural tour at the Stanley Hotel -- such interesting history there.
This is my personal favorite National Park -- one place to stay the whole week, plenty to explore, and such a nice sized National Park (so many beautiful alpine lakes and such a beautiful place). What I like about this place vs. other national parks is it seem I spend more time out of my car exploring vs. driving around, making it a perfect vacation. I always even moving to different loding places feel like I'm spending too much time in my car in places like Yellowstone that are just so vast (great trip still, but I prefer RMNP). We did a Bryce / Zion national park trip a few years back -- like that too -- again you spend a little more time driving as each park is more of a three day National Park vs. a six day, so it's two hours to Zion from Los Vegas, later three hours to Bryce, and then five hours back. Again, nice to do sometime, but RMNP is my personal favorite.
One east coast option that is on my to do list that I haven't done yet is spending some time at Bar Harbor/Acadia too. I'm looking at a trip there for August of 2017. That looks like an amazing place too and would be closer for you than it is for us.
