I have stayed at that Hilton numerous times using points...it is a good stopping place between tucson and houston, and since the hampton inn is never available when i am passing through, and I just can't seem to make it all the way to Kerrville or SAT, it is where i stop...It is difficult to find the hotel at night the first couple of times. I have driven through the airport a couple of times, having missed the turn...It isn't much easier in the day time.....I have never felt "nervous" really, even checking in late at night, but it definitely has an "interesting" vibe...Staff have always been nice to me (one lady has worked there for as long as I have been going there and she remembers me every time). The oreos and bottle water next to the bed with a welcome note is a nice touch
