Next week, the world’s rich and famous will descend on the small town of Davos, Switzerland. for the annual meeting of the World Economic Forum, which is essentially an invite-only schmooze-fest in the Alps.

Since the value of the Swiss franc rose 15 percent this morning, the exchange rate is going to make Davos a lot more expensive, Bloomberg points. Especially for Americans.

For instance, a Johnnie Walker Blue Label whisky at the Belvedere Hotel in Davos would set you back about $41. That’s $6 more than yesterday. And a double room at that hotel — at last check — would cost $1,133 each night.
