I would assume the vast majority will go home. I can't imagine that the team even really wants them to concentrate in one place (Clearwater) and all go to the same training facility, that is the definition of what we DONT want people to do (everyone get in a room, get sweaty, cough, get next to each other).
I think what was said earlier is clearly correct, pretend it is a strike that gets settled on XXX, YY (pick the date). Maybe a week or two of late spring training, 30 man rosters for a few weeks, get playing. You might even see some strange things line double games, where half the team plays in game 1, half in game 2 just to get everyone stretched out faster.
