I have been here a number of times, over the course of several years, when out of town guests come to visit. As a result, I have see the park expand dramatically over the last 4 years or so. There are new shows, a fancy hotel/spa, more restaurants and shops (including a CD-R King selling cheap computer parts!?), a new pool, bird exhibit, and so on.
This is a place where you can spend the whole day (and an easy $100 US per person) visiting all kinds of fun things. There is the expected fish exhibit, though the aquariums are old and not well maintained. The sharks and rays are OK too, though nothing spectacular. The "Big tank" with the walk-through tunnel is nice, there are lots of things to see and the aquarium is well decorated and in good condition, so there are lots of photo opportunities (please remember, No Flash). When there are a lot of kids, though, the noise is deafening in the tunnel.
There is an Antarctic exhibit with some penguins (you can feed them and get photographed for an additional fee), an ice slide, and a very large freezer with snow on the floor, decorated with snow and Christmas props, for photo opportunities (take your own, or get professional photos for a fee). Jackets are provided as part of the entrance fee, and you can stay as long as you like. On a hot day, it feels good to "chill out" for a while.
There is a "Dive with the Sharks", a "Glass Bottom Boat", and a "fish spa" where small fish nibble at your feet. These can be fun, and entertaining, depending on your preferences. There is a Jellyfish exhibit, showing different types of jellyfish, some in tanks with colored lights or mirrors. They are quite fascinating.
The Birds show and cage is also quite interesting, as it shows native species of birds of prey, and their skills at catching food "on the fly". The sea lion show is fun and entertaining, and worth the price of admission.
There is a "4D" (or maybe they're up to "5D" now) motion ride, similar to other theme parks, where riders are in a car that moves in 3 dimensions while surrounded by video screens.
There is, of course, the usual gift shop with lots of overpriced merchandise. Sadly, most of it can't be found elsewhere, so we usually end up buying some.
I have found that most exhibits will sell you tickets at their door, so there isn't any reason to buy them at the entrance. This way, if you look at the attraction and like it, you can pay on the spot, but if you don't, then you haven't already spent the money for it. I usually buy the 3-item package (600 php now) and then go from there.
