Ok, the Waikiki Aquarium does not warrant a special trip to go visit, but if you are already in the area and have 60 to 90mn to kill, it's still a fun visit. A few pictures below:
After diving nearby, it made sense to go check out Sea Life Park. It's a fairly small Sea World, but still fun to visit for 2 to 3h depending on how many shows/talks you go to. The actual aquarium bit is kind of small, though. The birds added some good amusement.

There were a couple of shows, one with Sea Lions and one with dolpins:
This is the 2nd aquarium we go to that has a nice little birdie collection. Those were very friendly and hungry :)
