Back with an update: We went on 11-12 and crowds were very low. We went to the first dolphin show and there was tons of open space. Went to the 12 pm show for One Ocean and that was filled but not packed. The sea lion and otter show was closed for the Polar Express Show still in production. The wait for Antarctica was only 10 minutes during the 5pm One Ocean show and we spent a lot of time talking with the workers. It's spring in the Antarctica and mating season was in progress. Very informative. It was a great day and the kids loves all the sea life.
