I am a AMEX cardholder but ANA is not listed as a transferpartner of Amex here in Sweden. I have recently transfer all my SPG points til my ANA card so I guess my only choice is to find some cheap hotel that would give me 500 points.

Edit->I just found out that I can buy 500 starpoints for 25$ but the problem is that I need a minimum of 2500 before I can transfer them to ANA. This means that option would cost 125$ and then it would be cheaper to get a hotel room somewhere.
