They travel on Friday afternoons. They do family Friday in the late morning. It's usually a pretty lean schedule, unless the game is a night game (then there is a bunch of dead time Saturday morning/early afternoon). They usually arrive at the hotel, pick up their keys, meet for dinner then have downtime optional stuff like team movie. They get up on Saturday and eat breakfast, have the walk through in the hotel ball room (or parking lot, if the hotel is smaller), and then off their feet until the bus loads to go to the stadium. They fly/ride back right after the game, even if it means getting back to Austin at a ridiculous hour.
they're about to start testing 2x/week with a 24 hour turnaround time for results, and contact tracing/quarantine for any positives. I'm not sure that travel represents a bigger risk than being in Austin. The team is certainly more confined on the road, with fewer exposures to those outside the controlled, tested, travel party.
