I said "No" but asked if they could change my booking to the "Flexible" rate, so I could pay on arrival; I even offered to rebook at the flex rate. Nice people: they agreed to me paying on arrival, without increasing the charge to the flexible rate.

(I shall have other card options by the time I arrive in Vientiane, or I could even get a large sack full of kip from the 'bank down the road'!)

I had the same problem earlier this year at Sofitel Luang Prabang, Laos. They wanted another card and said no, telling them that the cards info were correct and so they had to retry. And it worked, they managed to do it. May be a global Laos problem !
