How much is the entrance fee in Singapore's hot tourist spots?

I am from the Philippines and I'll be in Singapore by next month.
How much is the etrance fee for two persons (if there is a package for two) for the following hot spots:
Jurong Bird Park
Mandai Orchid Farm
Singapore Zoo
Night Safari
Sentosa Island
Underwater World
Cable Car Ride
Boating in Clark Quay
Please indicate so if I missed enumerating other places to go to Singapore with or without entrance fee and how much.
Please help so that I can budget things out.

Check out the packages on these websites! Otherwise, it'll be quite expensive to visit all these places. Have fun!(:






Answer :
I think it may be easier to search for these places of interest cos most of them have a website with the info you are looking for. And yes, some places do have packages for two.
But I'd say on an average be prepared to pay around S$25-40 for entrance fees.
Going into Sentosa island itself is only a couple of bucks but if you wish to visit each place of interest located in Sentosa, it's not going to be cheap. But I believe there will be some package offered.
Do check out their websites. It will be more informative,
