In hindsight, I should have put it on my Amex card and I would have got 2% cashback. This would have covered the charge.
Actually a friend of mine suggested to dispute *after* completing the stay. This way you're not disputing about the services provided (or the local currency transaction price) but you're disputing the conversion.
