For night Safari timing :
Mon - Thurs : If by 2315hrs u have not reach Night Safari,
forget it. By then the crowd have mostly dispersed. Last trip is
about 1215hrs and you can fetch 1 or 2 group of Night Safari Staff
back. After that no pple.
You can also try around the timing at 2130hrs. Cause that is
about the time of the first tram ride end. There is a chance of
pick and go at that time to 2200hrs. After that it is usually
waiting time of about 20-40min depending.
Friday and Sat : Although generally speaking, there are more
crowd. Still I recommend you reach Night Safari latest by 2330hrs.
This especially apply to Sat. Sat seems to have less crowd either
that there are more taxis to come and pick cause at 2400hrs, the
crowd is usually cleared. And if you are not half way in the queue
by then, you will not get the 0030hrs staff.
Watch out for events such as Halloween, Christmas, New year.
During last Halloween, I remember there was a series of night
events that last till 2am.
I never tried Sun before cause I dun drive on Sun. But
well,,....I think for Sun, follow the recommendation for
Mon-Thurs.
