What's the best way?

We are going with first choice on 7th August. I read on here that the transfer can take up to 4 hours on the coach. I know theres a comfort stop on the way but I've also heard the prices on these stops are a rip off, same anywhere I suppose on these stops. What would you recomend as far as drinks are concerned for on the coach, bottles of water etc. Are they expensive in the airport at Dalaman, if so what's the best way to take them from this end I just dont want to be drinking hot water when I'm on the coach.
