Traveled South from Hudson to Central Florida nov-dec 2007. Shallow draft so no depth issues. Almost always on the hook. Took the Virginia cut , Coinjock was very accomidating , Alligator River Marina was not-no services,no showers,and a dock master w/ a poor attitude.
Pungo creek (belhaven Area) has a small marina (who's name escapes me) single pier 2-300' long on the north shore just inside creek entrance, Inexpensive and very friendly, at the time they were planning expansion and replacing upland facilities.
Further south Oriental cannot be missed,they have a free dinghy dock,also small free city dock several wi-fi signals,some free some pay as you go, as well as an anchorage area.
Bucksport Marina just north of Geaorgetown was inexpensive ($1 a ft. overnight) or $150 a month !! It's my understanding that it is under new management and the rest. and bar are now open 7 days a week.
Georgia is best to go outside as the ICW winds and twists and is shallow. After you do it once you'll go outside afterwards. plenty of inlets in GA.
Spent christmas eve in Darien 8-10 miles up a creek, a little shrimp boat town w/ an historic fort nearby. City dockage available easy walk to grocery,etc.
Kilkenny GA. was another $1 a foot overnight. Not much there showers,1 washer and dryer, small store on sight-(soda ice cream chips) I believe they have diesel as well as gas. Restaurant nearby w/ dockage as well. otherwise 10-15 miles to supermarket.
Unless your sight seeing or just can't pass it up short hops up the coast would be my choice, as most of the services and such seem to be near the inlets and larger towns/cities , and of course no bridge issues.
