we just got back last week from two months in the abacos.
for wifi, you can't beat treasure cay. don't take a slip, just anchor
out in the mooring
area, about 200 yards from the marina. wifi is strong and FREE. we made skype calls home every day as well as doing lots of browsing. there's a pool right next to the dinghy dock
and right next to the bar. the bar gets a small crowd at night during the week, except on thursday (pizza night) when it seems that everyone in the neighborhood turns out. they also have entertainment but it can get pretty loud. also busier on weekends. i think for your purposes treasure cay may be the best choice.
of course you can anchor
in marsh harbor. if you anchor near union jack dock
you'll be near the oii (out island internet) antenna
. oii is a fee-for-service internet
provider. i paid $35 for a week of internet access. signal was pretty good but not as good as the free signal at treasure cay. oii has antennas all over the abacos so you've got a good chance of getting a signal from at least one of them. if you take a dock, i know that mangoes marina is inexpensive and has free wifi. marsh harbor has the biggest choice of night life (snappa's comes to mind) and some good restaraunts. don't miss junovia's restaraunt on don mackay boulevard. the best real bahamian food
in the abacos, as most locals will attest to.
the admiral loves hopetown. we spent two weeks there on a mooring ball. we were right off the hopetown marina and inn which kindly gave us free internet access for three days at a time, then we had to ask again, but they never refused us. they also have a beautiful pool with in-pool dining, and we ate lunch there often. nice town and island to explore as well. mooring balls are $20 a day.
i can't recommend great guana (settlement harbor) to you unless you want to stay at orchid bay marina, which is a bit upscale. they have free wifi for customers but no others. while it's true that nippers and grabbers are there - and grabbers has free wifi - it's just not convenient if you're working from your boat.
man of war is, of course, a dry island. 'nuff said.
that's about all i can think of at the moment. ask if you have any questions and i'll try to help.
