Great idea! It would also be helpful to list whether the property specifies a $ value (that can be applied to a full breakfast), and whether an upgrade option is given (or if the property is silent, check the menu and do the math). Also, any terms that are "above and beyond" the requirements (e.g., option for in-room dining) would be appreciated. I suspect we would also like to know which properties cut corners and give only a voucher valid at the coffee store instead of the restaurant, or perhaps define an excessively limited continental breakfast. Something along the lines of:

Property: XYZ
Voucher valid for: ABC items, $X at restaurant Y
Buy up to full breakfast: $X
Comments: Gives free full breakfast / gives breakfast and points / allows room service / only a muffin shoved into an envelope, pick up at concierge desk / etc etc
