When we drove to Alaska for the first time in 2011, we stayed a couple of days inside the park about the first of June(east side). Since the road was partially closed, we explored the east side pretty well, taking many walking trails.
On our return trip home in mid July, they had just opened the road all the way and since I didn't feel like driving anymore that day, I decided to take one of the green buses ( as I remember,they were free). On our way to the Pass, we stopped a few times to see animals or other points of interest and we only had a few other passengers on board. At the pass, the other passengers got off the bus to catch one going west, and my wife and I were then the only passengers left to go back east. The bus driver stopped anywhere we wanted for a short time and at one point she even let me out to take a picture, since there was no traffic behind us in the late afternoon. We walked back to the campsite from the visitor center. I'd rather stay in the parks and only stay at koa's as a last resort.
