i'm planning on flying to Kuching for a 10-day trip to Sarawak, going north, doing some trips upriver, stay at longhouses and visit Niah/Mulu caves. (i hope i can make it in such a time frame!)
after that is it practical to fly out from Brunei which seem closer on the map, instead of returning to Kuching?
or perhaps do this trip in oposite way, so fly in to Brunei and out from Kuching .
previous postings mention that road transport is slow and difficult up there.
after Sarawak i'm going to Singapore, so the budget choise of flying out seems to be Kuching. Miri seems not (which is also near Mulu) and i'd avoid an extra flight Miri -KK / Kuching because i 'll have so many flights already, so better do that overland, from Mulu to exit point.
i hope this question is not very complicated! what do you suggest?
