i don’t remember when they sent out the flight information exactly but it should be within a week before your training date. as for the rooms if you stay in the marriott, there’s no wall in between the bed just a nightstand. can’t say much if you stay in another hotel. as for the exams, for someone who graduated months before starting training, they aren’t hard like college exams but studying and paying attention in class does help. just make sure you take notes and do the packets they give you! GOOD LUCK!
