Lucky you are in Florida, you might get away with doing your method. In freezing climates, your patio will be way out of level the first winter.

The biggest mistake novices & lawn maintainance companies make on paver patios is improper base prep. Many try to use just a sand or stone dust base. It won't last long. You want a minimum of 4", preferably 6", of compacted CR6, CR8, #57's, or "road base". Leveled & plate tamped, followed with 1" of concrete sand to set the paver. Done correctly, it should stay level many many years.

All that said, if you are not making much for the install, go for it.
