Want to move to Cancun or Playa Del Carmen

Hi everybody!!
I want to move to Cancun-Playa del Carmen area..
I have 2 kids going into the 5th and 6th grade. They don't speak any spanish..that is one reason why we want to live there for a year so they can learn.
I would love to find a furnished place to rent for a year and preferably a school that would have some half americans or full american kids just so my kids don't get too home sick
thank you so much for any suggestions

I recommend you Playa del Carmen its very international town, more safe and better for living, most of the people here speak english, there are some english schools as well.
