Wow, congrats and nice to read about your experience! ^
I've never received anything for my 100th night years... never, ever. I have at least 12 100-night years.
On occasion I've received really nice gift baskets with Scotch, chocolate covered strawberries, bottles of wine, Whiskies, etc... but nothing like what you got!
Let's all hope this continues in the Starriott world.
