On a budget, weigh it — Warner Bros. Studio Tour Hollywood isn't cheap for what it is.
~$70-85
The thinking film-fan's alternative to Universal — a small-group tour of actual working soundstages, backlot streets, and the Friends and Harry Potter set archives, with a knowledgeable guide. It's pricey and structured (you can't wander), and there are no rides, so it's for people who care about how movies are actually made.
