Bernie is over there now. Good wifi at West End, Wifi in White Sound Green Turtle Cay, Treasure is excellent. The general wifi in the area is subscription and some places good and some not. Most of the triangle is good.
Friday nights met at Davids in New Plymouth. A great many of the local cruisers met there. Buy a bottle of wine and share some snacks, tell some lies.
GTC isn't as cruiser friendly as it once was. They did however have a great deal on dockage. What you ate at their resturants came off the cost of the dock, so if you have some crew or like dinners your dockage was free. That I don't think includes water or electric though.
Treasure Cay is a good anchorage for fronts, 10 bucks / day for showers, anchoring in the basin and good wifi as well as the pool. Lots enjoy pizza night I think Wednesdays.
Marsh Harbor can be loud as you'll find out. Harder to met people there. Lots of provisioning going on and loud music. Deeper to anchor by the jib room. I had a dinghy stolen there so lock it up!
