While travelling Malaysia last year we book to stay in Permai Rainforest for 3 nights. Once there we extending our stay to 5 nights as we loved it so much!!. We had one of the tree houses which are really great, plenty of space and aircon too! watch out for the monkeys in the morning. The resort have plenty of activities available which need to be booked 24 hours in advance....be sure to book early as most activities are done by staff outside there usual working hours. The guides in Permai are by far the best guides we had during our travels, very friend and helpful bunch of guys who love to show you their country. Restaurant had good food if you are planning a long stay you might want to venture out a couple of evenings as the menu is not very large. All in all a brilliant place to stay, I can't wait to go back for a longer stay!.
