I can't help you on that front, but fyi: I was in Naples, FL last March and noticed a guy SUPping at Wiggins Pass one day after a blow. Looked fun, might be worth a scout if you are looking for waves vs. flat water.
Aloha, I vacationed in Englewood Beach in March, took me FOREVER to locate a SUP rental. Finally found a Timpone Board to rent from a surf shop in Nokomis, do not recall name, but it was primarily a windsurf shop. You can probably Google search for it. Had a blast, and could not believe how many people were interested, and surprised that SUP has not really made it to SW Florida yet. Beautiful water, great to watch the fish and rays swimming under me. There was another guy renting them in Ft. Myers, if I come across the info I will post it.
