We were at Tuscany in October and everything seemed normal. Seating was pleantiful at both pools.
I know it’s not Seaworld but I’m assuming it would be about the same.
We actually visited Seaworld park, Discovery Cove and Aquatica while there. They were very good. Took temps at the gates, seating was good at the shows and beaches.
I think you’ll be fine and have a lot of fun. Resorts are like 2/3 capacity so not crowded.
