Yes, you do need a water taxi to get to town, which runs regularly, several times a day. About $5us, I think. I think they the public taxi does not run after dark, although I have seen guests hire a private water taxi for night runs. There is an easy land & ferry route for bikes, carts, and peds, and that too does not run at night. I've been to Morgan's and it was terrific. Plan on eating early and returning to Morgan's or eating at Morgan's.
