manneca: thank you for that feedback. Right now, I'm leaning towards Borneo. I would also be visiting both Sabah and Sarawak.
Which one of the river lodges did you stay at and for how long? I want to incorporate a visit to one or maybe two as part of my trip. I would be on the ground around 12 days total.
On Borneo, did you use a driver or did you plan your own trip and fly from location to location? How long were you there?
