If you or your buddy's are big eaters, ask the company to stock a little bit more food and offer to pay for it, $100 extra per person gets you a lot of food in indo. I travelled with 9 other mates and 8 of us were over 85kg (not fattys) and a couple of the boys were 100kg ish and we thought the meals were a little light on and we started running real low on food on the last couple of days. I ended up buying 15 packets of mie goreing noodles from the camp out the front of HT's.
Not all the surfers on boat trips are 55kg grommets
