Grand has a pump out too
Grand Marina has a pump out that is easier to get to by far, than either of the ones at Marina Village. Although a little practice on your boat handeling skills at Marina village would not hurt you occasionally.
I would be at either Grand or Marina Village, we are currently at Grand, and like it well enough. However the greedy owners have turned most of the parking lot into houses, so there is not enough parking here on any given busy weekend.
The marina staff at Grand are some of the nicest that I have ever dealt with, the Marina Village staff is nice too, but the Grand people seem to be a little nicer to me, both are way nicer than 95% of the marina staffs out there.
Nothing is very far from anything here on the island so I wouldn't worry too much about that.
Given the current status of the parking, if I were not living aboard, I would probably swap over to Marina Village.
Balina Bay is a dive and the most expensive on the island. The docks there have been coming apart for years, and since they are an Almar managed marina, there is NO upkeep, or repairs.
I would be happy to ask the marina staff here tomorrow if they have space for you.
There is also a park here at Grand, with a playground that your kids would love. It is between Fortman marina, and Grand Marina, and is quite nice too.
Fortman is not a bad marina, their docks are a little older, and wood, which is not as good as the concrete docks at Grand and Marina Village, but far better than the crumbling concrete docks at Balina Bay. Last time I checked Fortman was a little cheaper.
As far as yacht clubs go, you are on your own, haven't ever been a member of one, and don't see a good reason to become one, as my drinking is very light.
Also feel free to contact me back channel if you have more questions.
