I'm really hoping the weather in SE Asia in October won't ruin my trip. I know weather is unpredictable, but i have read mixed reviews about the amount of rain to expect per day. I have read that it usually just rains for about 1 or 2 hrs./day, then the rest of the day is usually fine, with rain about 3 days/week.
If that is the case it won't bother me so much.
If it rains for 4 hrs./day, 6 days a week, then i might have to pack an inflatable raft, instead of a waterproof jacket.
