Yes, I used BBX on occasion, just purchasing a three day access at a time. As Marin stated, it was very weak everywhere we went if you were near the edges of the marina.
We now use Clear (used to be clearwire). They are our wireless internet provider at home, and for a bundled price, we added the 3G/4G usb device that works real well all over the continental US. It always works better than the free wireless provided by most hotels. The 3G/4G is not cheap, at about $40/month. The 4G seldom works, accept in very large population areas.
