Where is/was this possibly defunct hotel in Arizona that I visited in '99 located?

I visited Arizona on a trip in 1999 along with a large group. While I was there we stopped at some kind of event that I believe was being held at a small hotel, either in Phoenix or an adjacent city. I recall that it was very flat, no nearby hills or mountains, and that it may not have been in the best part of town.

I took a few pictures, but unfortunately none of them have been sufficient to identify or locate this place. The relevant details I found include the following.

The pool had a logo on it with what I think are the letters "gr":

There was something that I think was a restaurant or lounge in the hotel:

I think this says something like "Gregory's Grand Avenue Club" so the name could include "Gregory" or "Grand" but searching for variations on this did not turn up anything. I also looked at Grand Avenue in Phoenix for anything that resembled this place but did not find anything.

I also have a picture of the courtyard - the pool was in this central area surrounded by building on all sides:

I suspect that this building may not exist, or if it does it no longer has the same name.
