Sent my reservation request to the Corner House via their website. Requested to reserve a single room for the first full week in October, 7 nights. I received this very polite reply:
"Dear you are welcome this dates
But contact my the month August
Regards.
The Cornerhouse"
Here in America, one can book a hotel that far in advance, even at small bed & breakfast joints. I'd like to book my room NOW, however this is perhaps a good time to learn what's different between Amsterdam and America.
I'll keep an eye on their website and when they have the 2009 availability calendar up, I may try again. (They still have the old 2008 calendar posted.)
