Sanibel, need a place to park a boat & trailer next week

[krash]

Going to Sanibel next week, 8/6 -8/11, my son wants to bring his skiff, a 14' Dusky with 25 (not a big boat, will fit in a parking space.

Staying at the SunDial, and they won't allow the boat in the parkinglot overnight.

Any suggestions of a Marina with in/out access, meaning we could get in early, like oh dark thirty, launch the boat at either their ramps or pull it out and launch at the public ramp. Back in the lot before dark.

Would prefer to stay on the Sanibel end of the Island, but Captiva will also work.
