DoubleTree is more popular because it’s United’s primary short stay training hotel, and it’s right across the street from TK. However, the Renaissance is a much nicer hotel. My first week of Indoc at the DT, I didn’t have a fridge in my room. Fridges were “waitlisted,” and half of the rooms are in severe need of updating.

I used Cage, and thought they did a great job. There is so much hiring going on right now, I think you’ll be fine with any service. From what I’ve gathered, they all have the same info and use the same techniques.
