Actually we were thinking about it! I live in Ohio and we used to have a Sea World here but it's been gone for a really long time so we had thought about going while we were there. But we also wanted to get in a day or 2 at Universal so it's kinda becoming complicated.. I don't know if one or two days is enough for Universal, if one is enough we could throw Sea World in then, I just don't know how to plan a trip there that includes more than just Disney cause I get selfish and wanna spend all my time at Disney!
I'm also from Ohio, and I worked at SeaWorld Ohio one summer. So I was really looking forward to taking my daughter to SeaWorld Orlando when we headed south. Unfortunately, when we went to SeaWorld Orlando in 2012 we were very disappointed. When I worked at SeaWorld, they had multiple animal shows throughout the day. For example, one was a "fun" show and another was an "educational" show, where they showed how they trained the animals. So there might be 4-6 shows over the course of a day, with 2 different themes for each. So you had a reason to see Shamu or the dolphins twice. Orlando, when we were there, had 2 shows per day for Shamu, and they were the same identical show.
Clyde and Seymore are always funny, but overall the shows seem to have gone downhill. And while the kiddo loved the shows, those of us who remember the Ohio experience were definitely underwhelmed. And, while we were there, no penguins.

Additionally, it seems like they are really trying to compete as a thrill ride park, not on the animals. They have roller coasters and other rides with significantly high height requirements. So while littles might enjoy the animal shows, there wasn't much for them to do between the shows. (But boy, did the 4 year old want to ride the coaster with the 54" height requirement).
YMMV, of course, but this group of Ohioans didn't enjoy SeaWorld Orlando nearly as much as we remember enjoying SeaWorld Ohio.
