My only experience with Amphibians is with the Lake Buccaneer. But it is a slow airplane. I don’t think that’s what you really want for travel. My preference for a travelling machine is that it be fast. To each his own, however.
You got me a bit curious about what is actually available around the Orlando area for rent.
Eagle Sport Aviation in Deland
https://eaglesport.org has a Pitts, a sailplane, and an L-16B (military version of a Champ)
Orlando Aero Club has a Citabria

Couldn’t find any sea plane rentals. That’s a rare thing. The one I was renting for a while had a pretty high renter’s insurance requirement. Point is, though, that there are rental possibilities for some interesting stuff in your area.
