San Diego native here, I sorta grew up at SeaWorld. The first time I saw Blue Horizons, I laughed. It seemed way too corny for the locals. I think it suits Orlando a lot better. The over the top performance works better there, rather than the more laid-back vibe from Seaworld SD.
Also, I know I may be in the minority here, but I haven't been to the park since Blackfish came out. I would go if someone bought tickets for me, but not pay my own money.
With that new Orca enclosure posted a few pages back...that may convince me to give this park another try. It looks ten times better for the whales. It still isn't the best, but it's better.
I miss that park a lot, and seeing it on a daily basis has reminded me of my fond memories of the place even more. I think I went every week or so from around age 7 to 16-ish. The last time I went was right after Manta had opened, and I got to ride it twice. My heart is so torn.
(Same with Six Flags Discovery Kingdom. Medusa is one of my favorite rides, but I don't want to give that park money after seeing how poorly their big cats are treated.)
Anywho, if those plans for the new orca enclosure go through, I can personally say that a lot of locals will definitely flock back to the park, myself included.
