Hi everyone, we are planning our first trip to thailand next year hopefully Mar/Apr depending on funds. We are a family of 2 adults, 2 girls aged 6,9 and one baby boy aged 18 months. Initially I was looking at one week Koh phangan/kohsamui, 1 week Khao lak. How ever from a cost point of view I am thinking 2 weeks in the one area doing different things might be better. What are other peoples advice experience. We are looking at mostly relaxing holiday with some day trips when we feel like it. Would it be most cost effective to stay in one area?
