Lots and lots of ATMs in Krabi, all over the place.
If by "Krabi" you actually mean "Ao Nang" as many seem to do, I can tell you there's one literally every 10 metres.
In Krabi Town there's one at a big bank on Uttarakit, the main street along the river, and others on the other main commercial streets.
In Koh Lanta, they're mostly in the village Saladan.
Last time I was on Phi Phi it was still wrecked by the tsunami, and on my previous visit there had only been one place to change money. Now I understand there are also plenty of ATMS. A more recent visitor could confirm that.
Thanks very much for your help.
