Thanks Doc for the info on the properties being part of the Amex Platinum. I just signed up for that card and had not seen the listing of hotels they are affiliated with. I just assumed that it would not be part of any of the 'chains', so didn't even think about that perk! I was just interested in which property treated Platinums better
. Checking both web sites, and other travel sites, it looks like there are lots of available rooms at a wide variety of rates (many discounted), so I was hoping to book a less expensive rate and get upgraded.
