When my wife and I went to Orlando a few years ago we went to Seaworld and
Discovery Cove. Discovery Cove is amazing. It is very low key, not crowded, very relaxing, beautiful... Not a bad way to spend a day! Swiming with the dolphins was VERY cool. There is virtually zero advertising on site. Its sort of like being in a private spa.
The only bad thing about going to Discovery Cove was that we went at the beginning of our stay. It is so nice that Seaworld (which owns Discovery Cove) seems really, really cheesey in comparison.
When we get back to Orlando again we will definately be going back.
