ICW Anchorage around FTL?

[Island Mike]

Need a little help, I am taking the family down to Key Largo area for Spring Break, my home port is Cocoa Beach. I can make St Lucie area easily on the first day, my intention was to head from there, jump to the outside at Lake Worth (if weather permits), I am unfamiliar with the no wake zones south of St Lucie, can anyone tell me if I stay inside where a realistic 2nd night anchorage would be, I cruise at 20k, but don't know if that matters down that far, do to bridges and "no' wakes. I like to limit the cruise time to 5 hours/day. Cruising guides are not very optimistic about finding anchoage between FTL and MIA, I am assuming reaching Elliotts from St Lucie is too optimistic a goal.Can any one who is familiar ring in. Thanks
