I did my ATP this summer out of North Las Vegas with ATP.com. It is a little fast moving in the short program but it ended up being about right. One "learn/screw things up" ride then a "fix your mistakes" ride and last the check ride.

I did my ATP written with them and my brain was mush after that day long pain. My score was in the high 90's but the pain is not worth it unless, like me, you did not have the time to do Sheppard Air (high pace deployment). I did Sheppard Air for my FE written and it was much better on the noggin.

I had a short practical with a FE that understands we transition through the seminole followed by a profile just like the one mentioned above. I think Vegas is a good option with easy airspace but the GPS approach has a little unnecessary pain. If anyone is interested in Vegas feel free to ask any questions.
