I was there 2 years ago...
Edmund's Oast is a must-stop. They have unique offerings that will suit any beer nerd, from "normal" stuff to sours & Belgians.
I didn't make it to COAST or Holy City but I am kicking myself for it, they should be very good according to reviews.
Westbrook is overrated. Their gose tastes like seawater, etc.
Palmetto is underrated. Their amber is a staple everywhere and it is very good indeed.
