I'm going on my first cruise in March. I'm on Seabourn Encore for 14 nights, visiting Vietnam, Cambodia and Thailand and I'd be grateful for some advice on how much cash I should take for when I leave the ship. From what I'm learnt, I'll need US$ for tips on the ship and for Cambodia. In Vietnam the Dong is used, but I'm not sure how many ATMs I will encounter, same for the Thai Baht. If you've taken this trip, I'd be grateful for your advice. Many thanks in advance.
