The ME a/c at my local aero club is basically unavailable for my ATP training. I'm running out of time (upcoming deployment). I have a reservation for the 2-day course at ALLATPs in Denver (Centennial) for 20-21 Sep; any reviews for that location? My one bro who did the 4-day course there a few months ago said if I'm doing the 2-day course, I really need to understand the Garmin GNS 430W and the DEN Class B airspace. He also stated the a/c were "immaculate" and nice with the G500 and dual GNS 430W cockpit.
