The Mirage and the Rio are my favorities. The MGM is the hotel version of airline coach travel. Off the strip is a nice Marriott, Courtyard I think. Quite quiet for a pleasent change in that noisy town.
BTW the 7-2-99 WSJ had an article re lowered Mirage earnings. What caught my eye, was that occupancy was 97% vs 99% last year. I thought it was crowded but now I know why they can hold their pricing at a high level.
