We did the Airboat & Jungle Adventure. We loved going off the beaten path and seeing the more 'wild' side of Florida. The Jungle Adventure was literally in an alligator shaped road-side attraction, straight out of the 50's. The staff was both informative and very passionate about thier work. Would definitely recommend it.
Blue Lagoon itself is a little slice of heaven...and would go back in a heart beat! We also did the Sea Lion encouter there...which was awesome. We got alot of time with the sea lions, and of course photos to buy. The staff was did a wonderful job also.
