I alreasy saw the 400THB and 40THB parks entrance fees. Where are these paid? We will enter using the North Gate and go to the Visotor's Centre as it seems there are some trails near there and, I assume, we can get some maps to drive to other trials further in the park. I am not finding much information at the moment, so I guess I just have to wait until we get there.

We will be driving there using my friend's car (Thai citizen). As I am a non-Thai citizen I cannot fathom if I will be legally allowed to drive my friend's car. I can buy a IDP for £5 from my local Post Office before I fly there. But I cannot find out if I need to be put on my friend's car insurance - that would be needed here in the UK. But I cannot find out what legal requirements are for a non-Thai to drive a friend's car in Thailand. If I had a rental car (which I am not getting) then all the insurance would be within the price.

I want to share the driving for two reasons: 1) my friend can relax a bit on the journey and 2) if I can work out the driving there for this trip then I can drive more with my friend on all other trips.
