Especially if you have more than a day to spend at LEGOLAND, it’s worth saving a little time for the Sea Life Aquarium, right next to the park entrance. The 4,000 marine inhabitants here include sharks, seahorses, manta rays and jellies. A “Lost City of Atlantis” theme adds a neat element, with one tank boasting a 10-foot tall statue of Poseidon and a seven-foot long LEGO submarine.
