Leaving for Japan in 13 hours and just received an email from our hotel saying they no longer accept Visa/MC. They say they only accept AMEX, Diners, JCB or cash. The total bill will be 120,000 yen / $1300. We can stop by the airport in the AM and get more cash, but I'm not sure how much we will be able to get. Anyone have experience with Discover card being taken as a JCB card. Searching online shows that it may work.
