In terms of concrete moving of business: While I will do the remaining stays needed to make Diamond because it'd be cutting off my nose to spite my face to do otherwise...

1. I transferred the $20 worth of AMEX membership reward points I needed to make Gold on IC/PC, and will check out a couple of HIX/CP properties in locations with no Hyatt properties (such as Janesville WI and Harrisburg PA) to start using if they are cheaper come 1/1/2010.
2. I broke a couple of 2-night stays into mattress runs to get to 28 faster, so I could
3. Give several more 1-night stays to Hyatt this year.
4. Am only using my AMEX Hilton card for groceries, pharmacies and Hilton stays. AMEX Starwood is getting all of it. AMEX themselves could care less.
5. Encouraged a co-worker NOT to stay at the HGI Midtown Manhattan next week. Four nights at $379/night went to a boutique hotel closer to our office instead, with an upgrade to a junior suite.
