I just went through the in house CTP course, it was a very easy process, and all the instructors were great. They put us in the Wingate during the ground portion in Indy, then they put us in the Marriott Res Inn in CVG for sims, which was extremely nice. They did split us between the 145/170 sims, but we each got 16 hours across 4 days in the full motion sims, and I learned a lot in the 170 sim. However, they were talking about bringing it down to 12 hours to free up sim time, and moving everyone to the 170 because they got a buyer for all the 145 time they had laying around.
