The Perot Museum is a solid stop if you're traveling with kids or enjoy natural history and hands-on science exhibits. Expect a modern building full of dinosaur skeletons, interactive displays on energy and engineering, and a decent aquarium section. Most visitors spend 2-3 hours here. It's clean, well-organized, and rarely feels overwhelmingly crowded except during school holidays. The giant slide and outdoor play area are popular with families but can get noisy.
Best time to visit is fall or spring when temperatures are mild and lines are shorter. Summers are hot and busier with vacation crowds; winter weekdays are quietest. Expect to pay around $25-35 per adult and $15-25 per child, with slightly higher rates for special exhibits or timed-entry slots. Parking in the museum garage adds another $10-15.
Honest tip: Get tickets for the earliest slot you can manage - the place feels better when it's not packed. Skip the IMAX unless you're really into the specific film showing; the regular exhibits give you better value. If you're short on time, focus on the dinosaur halls and the fourth-floor science exhibits.
