I think your million dollar donation and your choices of organizations is awesome. But how about keeping some of that money local in the US. Right now millions of people in the south of the US can use help.
I live in Texas and millions of people are still in horrible shape from IKE this past week. Some have lost their homes and business totally. People in Louisianna are still recovering from three years ago and have had new damage from Gustav especially in the Baton Rouge area.
I know these aren't hot travel spots. But, a lot of the people/travelers that make Trip advisor what is is live in these states.
Just something to consider especially as you are giving during this bad Hurricane time.
Didn't know how to contact the "powers to be" at Trip Advisor. So, hopefully someone will see this here!
