On a budget, weigh it — The Queen Mary (Long Beach) isn't cheap for what it is.
Tours ~$30-50
A genuinely atmospheric piece of history — an Art Deco transatlantic liner you can tour, dine on, and even sleep aboard, with popular ghost tours. It's showing its age and has had on-and-off closures for repairs, and Long Beach is a haul, so check current access before committing.
