I'm using the ramp on Sanibel. $9 toll for the bridge, $2/hour to park the trailer.
Do us all a favor and ask him to call Lee County Parks and Recreation and ask if he can launch from the causeway.http://www.leeparks.org/
A long time ago, we had a lot of cats launching there regularly. If there is renewed interest maybe we can regain access.
I've launched from Pineland but not in 20 years. My guess is they've done nothing to improve the ramp.
The kayak launches I've seen aren't wide enough for a cat and there's no place to put the trailer. I haven't seen the launch you mentioned.
We shoud get together, have a local "cat fest" of sorts.
