The park is actually quite small and there is little surprise in most of the attractions, as one can see the whole thing as you walk past. There is also no real common connection. At times things are just built out of Legos. Other times you are the size of a minifig. If you are trying to do everything, it could take a full "day" (the park is not open late) as there are a few 4D movies shown in the 4D theater and the water ski show (which has an odd, incoherent storyline that further confuses the issues of theme). Part of the Cyprus Gardens are still accessible to the public and have pretty much been left as is, including an alligator warning sign that still bears the Cyprus Gardens Adventure Park logo. Be aware that the standard procedure right now is for the park to be closed on Tuesdays and Wednesdays. Keep an eye on the weather, as almost everything is outdoors. Also, while it may seem like a deal, the all you can eat pizza, pasta and salad buffet should just be avoided, the food is out right gross.
As stated, the price right now is a bit steep. It may be worth it a bit more when the waterpark [re]opens, if it is included in general admission. If you are a member of AAA you can purchase discount tickets ($19.00 off for adults) at the Winter Haven AAA office which is not too far out of the way.
I would almost suggest waiting for the Legoland Discovery Center in Atlanta to open next year. It's about twice the driving time as compared to Walt Disney World to Legoland Florida, but the admission is likely going to be much less. The one in Chicago looks to have plenty of offerings but only costs as little as $10 online or $20/adult and $15/child if you walk up and purchase your tickets.
