I’m about to answer the two most asked questions. No, there is no air conditioning. To use the toilet we hike to the visitor center which has public restrooms. However, in the event of an emergency we have a sawdust toilet which works like a human litter box. Two buckets: one with sawdust, the other with your business. Cover up your business with a scoop of sawdust because it’s your business and no one else s. The sawdust will limit the smell and bacteria. We’ve never had to use it because this is only for emergencies and we run a calm ship, even though we’ve had some empty threats for presents left in our commode.
