Pretty sure, I left before noon, so maybe things changed later on. It also was weird because Manta said 25, but it was roped off and there was no attendant there. Never saw it run. Antarctica said 0 for riders and 30 for non-riders, long queue line, pretty sure the ride was not open. Wild Arctic said animal exhibit open, but ride closed. Went through Turtle Trek, exhibit was open but the theater was closed. Journey To Atlantis and Infinity Falls both closed completely, did not even have water running. Not sure about Sesame Street, I know some rides were running there but not sure if all of them were. Stingray lagoon was sealed off too. Not sure if you could walk up to the dolphins.
To be honest it was rather sad, but then since it was Seaworld I had low expectations lol. And on a good day seaworld is already slow at dispatching its rides, so now ... Was going to wait for Mako, but after a minute decided to get out of line, with no fans on, I did not feel like just standing there in the heat. Also seemed like most of the stores were closed. Most people wore masks, though you did see more maskless people than in Universal. In front of the turnstiles it also was the usual heap of people.
Seems they really rushed to get open, hopefully they'll get better at it. They probably lack a lot of employees at the moment too. I feel bad for people who paid for a ticket.
