how long were you able to watch , what were the crowds like , is the glass clean

sorry for the late reply. unfortunately, it's not too long. there was a big crowd. so, at most 5 minutes per panda.

but you are allowed to stand behind the barriers for as long as you like. we stayed for about 15 minutes behind the barriers taking photos.

unfortunately the glass is extremely reflective. so, you'll get lots of reflections when taking photos.

the glass was relatively clean when i was there. but we were quite early.

make sure you bring a very fast lense as flash is not allowed. and maybe a long zoom lens. regretted not bringing my 70-200.

we'll be going back again on another day to see the pandas again.

yes, eztephen. that was exactly what i was thinking as i was trying to take photos.
