Tours can often stay in town for a months run or longer -- depending on the city. Jersey Boys will be in Boston for 12 weeks! The tours get transportation TO whatever location they are performing, and are put up in hotels nearby the theater. If the cast members want transportation OTHER than that...they can rent a car (well, most of the cast of SA cannot as they aren't old enough) or arrange for other things. An out of town tryout would follow those same guidelines.
If a big name person tours, they can arrange just about anything possible into their contracts...including a car. But that't no different then negotiating for a b'way contract.
I would imagine that for an out of town sit down the same is true: get what you can IN your contract but for the most part that is your job and therefore your responsibility to get to and from work and your living arrangements.
If we're not having fun, then why are we doing it?
