Only 11 nights on the boat. We've done the same trip before on a 10 night charter and it was a bit of a whirlwind but still fun. We don't intend on spending much time in the SVI and USVI - probably just one or two nights in each direction and maybe even skip the USVI altogether. Of course conditions might dictate otherwise. We wanted to charter out of the BVIs but the SJU>EIS flight was a killer and the boat was also cheaper out of Puerto Rico. It'll be an adventure.
