Saw this at my local Costco, and apparently it's available on Costco.com as well:
Enjoy 12 Months of unlimited admission to LEGOLAND® California, LEGOLAND Water Park and SEA LIFE® aquarium
First visit on or before March 31,2020
Blackout dates December 26, 2019-January 1, 2020 and December 26, 2020-January 1,2021
Two 1-Day Resort Hopper Buddy Tickets valid through March 31, 2020, blackout dates apply
Delivered via email
For us (family of 3), we will probably get 2 passes and use the 4 buddy tickets for all three of us to go 4 times. The only downside is the buddy ticket is only valid until 3/30/2020.
* Parking not included.
