It's been almost 4 years since I did new hire training. Travel and expense to MIA was the responsibility of the new hire. I don't know if that has changed.
I chose to drive my car all the way from MN. I wanted wheels and freedom. I was reimbursed for mileage, but only for the return trip to my home. Frankly, I was in the minority maybe one or two other people did the same.
I wanted the ability to get away from the hotel. You can have a life during training and study, too.
