Convert back from BTC into a local currency, efficiently I receive rent income in the US. I'm using coinbase.com to convert from USD into BTC, with no problems.

I will be traveling outside the US, so I would like to convert back from BTC into a local currency. (I'm going to Ecuador; there are several exchanges but they seem set up for people to buy BTC.) 

What I want is to convert from BTC into the local currency. What is the most efficient way to do this? (I may need to do this several times, which is why I'm interested in doing this efficiently.)

How should I set it up?
How about localbitcoins.com?
