I was looking at the Park Hopper tickets on the Singapore Zoo website but was keen to get more information on how it works.
It looks like if you book online you have to select a "Park Hopper" date and also a "Night Safari" date, does that mean you have to lock yourself in for dates to visit the zoo before you go? Or can you just go any time within the 7 day window (but only once per park).
Is the Park Hopper option only available online or can you walk up to the ticketing windows at Singapore Zoo and buy the 4 park admission ticket at the counter for the same/similar price as online?
Can it all be seen in 2 days or is it best to split over 3 to avoid rushing? I was thinking Singapore Zoo and Night Safari on day 1, and then River Safari and Bird Park on day 2?
