I did the Singapore Zoo, River Safari, and Night Safari on the same day in 2017. Arrived at the Zoo at about 10:30, did all of the Zoo's animal shows, and finished at about 6pm. Then ate dinner and entered Night Safari at 8pm, finishing the walking trails just before midnight. Yes, I was really, really wiped out when I got to my hostel that evening! But unlike Chili, I was thoroughly impressed with everything! I didn't think the Night Safari enclosures were too small at all, and I loved River Safari's boat ride. Like SnowLeopard, I was considering how much fun that boat ride is for kids! The only animals I had difficulty seeing from the boat were the jaguars. I did not see any beavers and wondered if they still have them.
