I think it will be denver thats stays, just too much to move that facility and I think they have some other issues with moving that many sims.
Bit of a drive from dia but never find it to be that big of a deal. As far as the neighborhood I have had no problems while running behind the hotel and no problems while heading out in fron to different places to eat.
I understand some have but a lot of people go out there all the time.
