It all sounds great! Breezy Palms is a nice place, keep us posted Briguy.
Also, if anyone wants to take a break from fishing, there's the Islamorada Island Festival happening that weekend at Founders Park, MM 87 Bayside, 10-5pm.
Any arrival time is good at the campground.
If launching at Harry Harris Park & coming to Snappers or campground, here's an aerial of the location. There is a narrow channel coming into Snappers & it's only 18" deep at low tide until you get past the little bouy on port side, then deepens. Most boats go in & out on plane, but the first time it might be good to take it slow & easy.
