I have traveled a lot with my little ones so I have some experience here. First of all since you are going out of the country I think you should plan on bringing lots of diapers and lots of kid friendly food. If you are staying at a very americanized resort you may not need so much food, but you know how picky little ones can be... but the diapers you will be able to get are either really pricey (from the resort) or not quite the same... remember you are going to a very poor country.
You are also going to want to find out what they have for children to sleep in, if its an old crib... you may want to consider bringing your own pack-n-play or plan on your daughter sleeping on the floor. Some of those things are seriously scary... Many hotels now have pack-n-plays that they will loan you but I would check on that.
Other than that, just bring stuff to have fun, DVD players are great if they will sit and watch, coloring stuff, books, and favorite dolls etc are a must.
I agree with the other mom that said its pretty hard to child proof a hotel room, you just have to watch them closer.
Have fun and bring lots of sunscreen!!!
