We really loved the cabin at Sunnyside! It was very clean! The kitchenette was very convenient and we used the grill they had available!!! I only wish their WiFi was more reliable as we couldn’t get a signal inside the cabin. As for being on the Island Explorer line, you had to walk down Rte 3 to the Oceanarium to get it. Not super convenient and kinda scary!! Overall, we loved it and would stay again!!
