Thai Family Holiday Ideas

[magnusvv]

For my next holiday in October I am thinking about travelling with a small group of thai children to take them on their first real vacation. Similar to my trip to Mae Wong with a carload of kids, but this time it will be about 4 children heading to the beach.

I have been leaning towards the idea of Hua Hin or Cha Am because of their proximity to Bangkok, and I've never been to either. Since we will have about a week or so I was hoping to rent a house and even better would be one with a pool. I checked the internet, but so far I've found only monthly rentals and not weekly. My budget would be between 10-15k baht for a 1 week rental.

Can anyone recommend an agency? Better ideas than this?
