<human>: Hi reddit, as part of our school curriculum (we're in 11th grade) we have to plan and take a 1 week unaccompanied trip to somewhere in south-east Asia. We have 3 months to plan it and we have a budget of 1000 Singapore dollars (or about 700 USD) we have to book flights and accommodation with this money.

We have no clue where to go and what to do as we have to incorporate some sort of action activity in to our week, eg. white water rafting, kayaking, mountain climbing, biking etc. The only idea we've had so far is downhill longboarding as we're all longboarders. Aside from that we have nothing, we would really appreciate if anyone could give us some advice as to what places in south-east Asia are nice and cheap and what activities we can do that are maybe a bit unusual.

Provide a brief overview of the text.
