Sheila and Pam, I have to go with the others, the Grand Hyatt is great hotel. Nothing bigger and grander than any other, but a few years ago (on CAMEL, Sheila was on but says she only transited thru Dubai) almost all of us stayed there as I remember.
Peteropny (our friend Peter) gave us a link to a great deal at the time. Or maybe it was Suzanne. Anyway, perfect hotel for our group, and we organized one of those desert safaris. Loved it! Dune bashing and all!
