Manila Ocean Park is claimed to be the country’s first world-class marine theme park and a premiere educational facility. An integrated urban resort with marine life attractions and aqua-themed hotel, the park is geared towards an all-year, all-weather destination for locals and tourists, opened on March 1, 2008.
In terms of floor space, the 8000 square metres oceanarium is larger than the Sentosa Underwater World oceanarium in Singapore. It features a 25-meters underwater acrylic tunnel. Here is the map of facilities: jm-gm-pull-up-1.

I got a deal from http://www.ensogo.com.ph/manila/manila-ocean-park-seabreeze-08152013.html then only paid Php 600/person to enjoy SEA BREEZE EXPRESS which covers 8 attractions (Oceanarium, Sea Lion Show, Marine Life Habitat, Musical Fountain Show, Jellies Exhibit, All Star Bird Show, Birds of Prey Kingdom, Penguin Talk Show).
Perhaps because it was indoor theme park (not much affected by heavy rain), MOP got lots of visitors on that Saturday afternoon. Alif had a good time although it was a bit disappointing for him that Manila Ocean Park was much smaller (and less entertainment) than Hong Kong Ocean Park. We stayed there until Musical Fountain Show ended at 7:00 PM.
