As you're coming from the west, going to Estes Park and then into Rocky Mountain NP is a bit of a double-back. Suggest you enter the park from the west via Grand Lake. Beautiful drive!
^^^^^ This.
August is a madhouse zoo in Estes Park. Grand Lake and the west side of RMNP is the quiet side of the park, but still gives you access to what you may want to see/do. If you're into hiking, there's good, though long hikes on the west side. Or you can go up and over Trail Ridge for a day trip to EP, take the shuttle to Bear Lake and hike that area if so inclined. There's also Old Fall River Rd that, if open, would be a great loop trip (it sometimes doesn't open until July).
There's 2 commercial parks in the Grand Lake area, several USFS CGs, and Timber Creek inside RMNP. Timber Creek is first come/first serve only, cannot make reservations there. I've never seen it completely full, even on weekends. A great place to set up a base camp.
