If your DH wants lots of rides, perhaps you can fit a trip to SeaWorld's sister park Busch Gardens Tampa Bay into your itenerary. We were just there last week and it was fabulous! We rode Sheekra, the new diving coaster.... only complaint was that it was too short! We also rode Kumba... by far their best coaster, and Montu-- similar to Kracken--, Rhino Rally, Congo River Rapids and another one of the water rides. We skipped 4 of the coasters... The Python-- a corkscrew coaster- the 1st coaster built at Busch Gardens, The Scorpion-- has one loop and many flat spirals , The Cheetah Chase-- a wild mouse ride recently imported from another sister park-- Busch Gardens, Williamsburg, and Gwazi-- a dueling wooden coaster that is pretty wild! Busch Gardens is a beautiful park with plenty to do for the younger kids, as well, with Land of the Dragons, and another kiddie section, not to mention the fantastic animals!
If you get the chance, Busch Gardens is about an hours drive west of SeaWorld off of I-4 in Tampa and well worth the drive!
