If you love the nature more, you should definitely assign at least one more day for Everglades BP, it is a huge park, several entrances, tons of bird and crocodiles. Very very fun!!!
I went there two years ago, and I spend 2 days for Everglades, and I regret so much that I didn't have more time to stay there. I wish that I cut down half of the time spending in Disney's.
Personally, I don't like
3月8日:Magic Kingdom
3月9日:Kennedy Space Center
these two places that much.
