PDLM: Do you just leave your passport with someone you don't know? I value mine too much; especially when I'm in a foreign country and need it to get home.
jgl: Thank you for the answer I was looking for. We aren't sure if we want the bikes to do the trail mentioned above or just to get around all the villages behind Mui Wo since it might be the faster way to cover more ground. Do they supply helmets and locks too?
