It really is the only way to see Denali Park and that is to plan a stay in their camp grounds. Still cheaper than the nearby assorted private cabins. The weather often there is chilly cold and rainy though. The Visitor's Center has the public bus passes and general park information as well as getting a back country pass.. For years I would take the public bus, get off in the park, backpack, hike and camp out and catch a bus back. One can take their bike on the bus with them. I do not find the food in the area all that great so I pack a cooler and it is easier to eat instead of going "looking' for "eats". I take my Jet Boil for cooking. Best trip was my bucket list of 8 yrs ago. I won the Denali Road Lottery, had got a gorgeous day in September and took my inflatable kayaks with a pal and drove the 90 miles into the park kayaking the famous Wonder Lake in the shadow of the great mountain. Bad part, the most mosquito's I have ever encountered.
