They are similar, but I like them both. I like the connection with the whales in One Ocean, and love the "fun" of Shamu Rocks. We do both if we are there all day. It leaves you with a great fun feeling leaving the park in the evening after listening to some great tunes.
Kind of similar. One ocean is more educational about the whales and shamu rock is a fun splash fest. With fun rock music. I like both cause I love orcas so I see both but if I had to choose just one shamu rock would win.
