Ecuador is surprisingly well built up. It was definitely my biggest surprise when traveling South America. People who know it mostly from the economic collapse around the turn of the century will be surprised at how much progress they have made.

As an added bonus for US travelers, they use the US dollar as their primary currency. No obnoxious money exchanges to deal with! The only thing to watch out for is change, because Ecuador mints some of their own "dollars" that obviously won't be worth anything in the US.
