We are a family of 4 with two sons 16 and 20. We will stay for 2 nights at Miyajima during next month. Can somebody please advise me what is the best choice to stay, between a family cabin at Tsutsumigaura or the Seaside Hotel? There is also the possibility of staying partially at Morinoyado. Should we try one night here and the other at one of the beach locations? What is the best place or combination, please? Thank you very much.
