Beartooth Highway
You could also stay in Gardiner, MT. It's a bit rough around the edges, but it's right on the Park boundary.
Place to see in the Park: Hayden Valley, Lamar Valley, Canyon, Firehole Falls, Mid Geyser Basin, Old Faithful, Norris Geyser Basin, Mammoth Hot Springs, and tons of other stuff.
Whoever built that road wanted to get to Red Lodge pretty darn bad!
Also a gas station just south of the Park boundary in the no-man's-land between GTNP and YNP at Flagg Ranch. In GTNP, there are gas stations at Jackson Lake Lodge, Moose, and Colter Bay.
In short, plenty of places to get gas. Don't get fooled into thinking it's the wilderness
In the summer, the Beartooth Hwy is the only way to get to Cooke City from the eastern side of the Beartooth plateau.
In the winter, Beartooth Pass is closed, which means the only road to Cooke City is in the Park, from Mammoth. And so the Park Service has to plow it, at great expense.
But, it is the only road open in the Park in winter, which means you can see the gazillion animals in the Lamar Valley including the Druid Peak wolves, as you dodge the fuel trucks and UPS vans going to Cooke, that is.
The number of things I did wrong on that trip are too many to count.
