Okay, we've been B A D.
We see a tasty burrito/cocktail thats out of our price range, we just can't stop ourselves. One minute we're looking whistfully through the restaurant door, next minute we're there - prime table, huge goblet of pina colada in our hands, heartly laughing and .... okay, maybe not that bad. The good news for us is that we have a set amount of money going into our account every month and as soon as that's gone it's gone, therefore there's no real danger of us spending everything on a bad, two tonne gold replica of some Mayan temple after some tequilas. And so I'd recommend filtering in the money to anyone about to leave.

We've got travellers cheques and a credit card if we get stuck and the combo of all that seems to be working pretty well so far. With the travellers cheques and the monthly money we've got about $25 a day for the year and from what I've seen of prices so far that is totally do-able.

Our ATM cards are the Cirrus kind and there are not so many machines that take them, Visa/Plus is much more popular. However, that said, we've only had one situation so far where we haven't been able to use our card and had to change travellers cheques instead and that was because the atm machine was broken. The books say El Salvador is a problem but we just got a lot out in San Salvador and didn't hardly spend a thing on the coast because it was so cheap (happy days for the budget!).
