We (my wife, sons (13/11), and I) just got back from the Christmas holidays at Sea World and Universal. Had a wonderful time!!!
Don't miss:
Blue Horizons Show: Our favorite show, one of the best we've seen anywhere. Great blend of animals (whales/dolphins), human performers, music, and storyline. Very well done.
Clyde and Seamore Show (Seals): Very fun show. Go 15 minutes early to see the mime pirate pre-show. He's a blast!
Pets Ahoy!: Very cute and VERY well coreographed show.
We were a bit disappointed with the killer whale show, Believe. But go anyway, you guys might like it.
Rides:
If you like coasters, do Kraken. Nice, smooth, but fast. Lots of fun.
Journey to Atlantis: AWESOME ride, but February will be a bit chilly to ride it (it's a water ride).
Very beautiful park with very friendly, helpful staff. Have a great time and let us know how things went!
