I have a similar price target when it comes to business stays - not anything the company mandates, but just a personal preference. Despite their major points devaluation, I still prefer the Hilton chain as I try to book all my stays at HGI's - very consistent product across the country. Occasionally, price target permitting, I'll try out a new Hilton chain and the like, but I've found the product to vary drastically by property.
Regarding use of points - lots of nice properties situated across the world, specifically the Conrad and Millennium properties. Redeeming points next year at Conrad Koh Samui (pre-devaluation), Conrad Hong Kong, and a cheap paid stay at the Conrad Bangkok.
With that said, I'm also going to try out the SPG program for some award stays, since I'll have 30k points by end of next month with the new CC offer.
