Depends on what you mean by free. It's not as if Han thinks of being on the Falcon as 'confinement' or anything, but it is an enclosed space with a lot of time where you're drifting from one place to the other. In that time he reads, tinkers with something mechanical, plays holochess with Chewie, sometimes he'll dig out a remote and practice his marksmanship.

It's fortunate for him traveling can be done with such high speeds that he's rarely ever flying for more than a few days at a time. It keeps him from being static for too long - in the air and on the ground.

"Both." He says as his lips curl into a smile. "These days I'm getting good enough that I don't have to cheat anymore. Matter of fact, I won my ship in a high stakes game."
