I went there just now, and I must say I am quite impressed. Admission is $2 and the Cool house is accessible only through the national orchid garden.
The Cool house is extremely humid as there are misters operating all the time, your cam will get wet after a while. The temperature is about 20C, not too cold.
They have almost every popular type of CP except VFT and Pings..
Okay here are some pics ( for more, go the my photpg: http://community.webshots.com/user/vistary )
