@korhoen very busy. Since the volunteers by the panda entrance were saying the night house was open it got very choc-a-bloc. My suggestion is check often if it's open, and if you do end up going at the right time, wait it out. Towards the end of the slot the keeper announces they're closing it soon and most people leave then. The tarsier is slightly shyer than the cuscus, who didn't seem phased at all by the crowds.
@ShonenJake13 I can imagine it can get very crowded, especially with the number of people that visit each day this summer. The house didn't seem big at all from the outside.. I wonder if they'll ever get 'round to opening it full day?
Saw both today, the house was open when we checked about 2:15 pm and stayed open until past 3pm. Tarsier was very active but hard to spot, just as you get your eye in it moved. The cuscus showed really well - there were decent crowds but not too bad today.
@Javan Rhino good to hear the tarsier is getting adjusted. When I visited he remained where he was sat and reacted to every little sound he could hear. The cuscus really doesn't seem phased, it's just the tarsier I'm worried about. Perfect honeymoon gift for you and AG I imagine!
