My son and I have gone to Orlando Watersports complex in Orlando and have had a great time.
Check out their website

I was told that they are going to build another one in the Tampa area and should be open in about a year.
We have seen kiters there quite often perfecting their board skills. For a newbe it's ideal to get started wakeboarding. They provide boards with admission or you can use your kiteboard. We usually remove the fins to enable easier switching and to go over some of the kickers.
One of the staff mentioned trying to put together a special kiteboarder session. They have actually changed the lines on the cable to be much shorter than normal. I think they called jungle line or monkey line. This would allow you to boost very easily in the turns and give you more of the feel of kiteboarding. Anyone interested?
