About each park

Seaworld San Diego

SeaWorld San Diego sits on the shore of Mission Bay in San Diego, California. It's the original SeaWorld park, opened in 1964, and blends marine-animal exhibits with modern coasters: Emperor (a floorless dive coaster), Electric Eel (a triple-launch coaster), Manta (a launched family coaster), and the newer Arctic Rescue straddle coaster.

Southern California weather keeps SeaWorld San Diego open year-round, with peak crowds during US school holidays, Halloween Spooktacular and Christmas. Weekdays in January, September and October are dramatically calmer. Check live queue times for Emperor and Electric Eel on arrival, and use our crowd calendar to pick a midweek day for shorter waits. The park pairs well with a full-day visit to nearby San Diego attractions.

Universal Islands Of Adventure

Universal's Islands of Adventure is widely regarded as one of the best theme parks in the world. Its line-up blends record-breaking coasters with detailed themed lands: Hagrid's Magical Creatures Motorbike Adventure, Harry Potter and the Forbidden Journey, VelociCoaster, The Incredible Hulk Coaster, Pteranodon Flyers, and the classic Jurassic Park River Adventure. The Wizarding World's Hogsmeade is the park's most iconic area.

Like its sister Studios park, Islands of Adventure stays busy year-round, with Hagrid's and VelociCoaster consistently posting the longest queues. Peak periods are US school holidays, Halloween Horror Nights and Christmas. Check live wait times immediately on arrival and head to Hagrid's first. Use our crowd calendar to pick the quietest possible date for your trip.
