Question about USPS training?

USPS offered me a job for a Casual Clerk, I'm jobless so taking it of course. I got to take my drug test on Monday, and I was told training will start on the 21st which is next Saturday. He didn't say how long it lasted or much info about the training except it's about 1 1/2-2 horus away from me. Do they pay for the hotel? Do I get paid while I'm training? I'm sure I'll find out more info after I pass my drug test but I just wanted to be prepared. Thanks in advance.
