Hi Marc. My DW and I go to SW every WDW trip and this past year we tried I think it was Seafire Inn (or maybe it was Voyager's Wood Fired Pizza). Not sure if I'm picking the right name of the restaurant, but it was more like a cafeteria style, where you could choose from burgers, pizza, salads, etc. Be prepared, like Disney, food is quite expensive. I think we got a couple of slices of pizza each, and I got a chicken parm over a bowl of spaghetti, a slice of chocolate cake, and 2 drinks and the total came to almost $40. There are dining "experiences" also to choose from like dinner with Shamu which require reservations and an additional charge. Probably not the best option if you are tight for time. It's very difficult to see all the shows, as a couple overlap like the blue horizons show might run concurrently/ overlap Seamore & Clyde. Get to Shamu Stadium early as the shows fill up. And just a tip- sit to the upper half of the stadium if you don't want to get soaked!
I'd suggest going to the SeaWorld website and do a little bit of research...it can only make your planning experience a bit easier. Hope this helps.
