A regular ticket grants you access to LEGOLAND California Theme Park for a single day. In contrast, a Hopper ticket provides more flexibility and value. With a Hopper ticket, you can access multiple attractions on the same day, including LEGOLAND Theme Park, SEA LIFE Aquarium, and the Water Park. If you have a 2-day Hopper ticket, you can visit all these attractions on each day of your ticket. This allows you to hop back and forth between the attractions, making the most of your visit.
