The Lilypad is the best place to stay in Newport! My boyfriend and I stayed on the boat for a weekend get away for our anniversary and couldn't have asked for anything better. Danielle is so sweet. She is very easy to contact during your stay. The Lilypad is fabulous. We were lucky enough to get great weather and spent most of our time on the top deck relaxing in the sunshine (when we weren't out exploring the town).
A note for people who may be afraid about motion sickness: I have motion sickness and was totally fine! The Lilypad was docked during our stay (because of the off season) and after a while you couldn't even feel the small movements. I say go for it!
