I am so excited that you are adding a day at SeaWorld to your plans!

You know that park holds a special place in my heart, and honestly.....I think you'll love it. It's so relaxing and low-key......much different than a day at Disney or a day at Universal. Sometimes, you need some
fun without the frenzy on a trip

.
We are BIG fans of the all day dining plan at SeaWorld, its an EXCELLENT value

. An entree is going to cost you $10 or more on its own. Drinks are $2.50 or more. Snacks and desserts are about $4 each. You'll be well in the money if you eat two meals there. One August visit, we drank our plan value in water bottles alone. There are lots of great options as well, much more than just burgers and fries. Check out the menus at each place, choose well, and I think you will be pleasantly pleased. Its so nice knowing that you can eat what you want, when you want, all day long and never worry about the cost!
The restaurants are located all over the park, so you're never far from sustenance. If you have any specific questions about SW (or the dining plan), feel free to toss 'em out to me!
