See what is open too as in February there was a lot closed in Hollywood Studios still.
2 days in Disney seems very little. I would struggle to choose as like different parks for different reasons. Mind, I would scrap Seaworld. When we have longer we prefer to do a day at the Space Centre rather than SeaWorld.
Epcot - more gentle day, but a full day imo. TestTrack is our favourite here, and DD really likes Spaceship Earth for some reason. Soarin' was closed when we last went but will be open for summer iirr. We enjoy wandering round the different countries, trying out their drinks and going for a nice meal at one of them.
Animal Kingdom - I like the animals so always worth it for me, and we really enjoy Everest, and the two shows - Lion King and Nemo.
Hollywood Studio - one of DD's favourite places to eat is the 50s diner here. And we like Rock n Roller, Toy Story Mania, and Great Movie Ride. Not into Star Wars so that bit doesn't interest me. We enjoy the Indiana Jones show too.
If you did two long days you could fit Universal into two days - even more so if you paid for the Express passes. They can work out quite dear but they really really shortened your queue ride - so the only thing to queue for is the two Harry Potter rides, and the train. We got them free with our hotel on our last visit and it was fab!
