I won't bore you with the details, but I figured out that over the last 365 days, I'd easily be willing to pay $1200 for the benefits which I received as a Diamond. Face price of what I received is probably closer to $3500, but I wouldn't pay some of the suite rates, breakfast costs, or internet charges.
That's almost all domestic travel, plus breakfast for two plus internet for two nights at the Park Hyatt Zurich.
