Hotel Sosoro Merak is the top choice for a rest stop during your ferry crossing. Bringing families with children is guaranteed to be a blast, with free access to the Sunset Mall (rainbow slide, swimming pool with ferry views, white sand slide, etc.). The rooms are clean, cool, spacious, with large bathrooms—all in all, comfortable. Finding food and snacks is also easy (since the hotel is inside the mall and also accessible by ferry).
If you're planning a long journey to Bakauheni, Hotel Sosoro is the perfect choice.
Hope this helps.
