Hiya .. you will love Guavaberry and they have just build new villas so it will be fabulous. No sargassum seaweed at that side of the Island .. so all good there. you will have a magical time. We go there all the time .. for boat trips we always use Bradley Powerboats at Leverick Bay, they offer join in charters where you go with other people for a fun filled day out, and small personalized groups. They also do private charters and boat rentals, we also rent a dinghy from them and explore the North Sound with a picnic which is amazing. Call Elaine there she is amazing and will make sure you have a magical day. Enjoy :-)
