Avalon Undersea ExpeditionHere’s one luxury that isn’t reserved for the one percent: Taking your kids into the ocean, rather than to an aquarium, to learn about marine life. For $24, the Undersea Expedition tour off the coast of Los Angeles offers an up-close view of Pacific fish and plants in their natural habitat. Each 45-minute tour comes with a guide to identifying the myriad creatures swimming (and sometimes, bumping into) your window.
