UPDATE: The bathroom was dirty. The women's was even LOCKED. I understand and acknowldege your technology issue. You should have a backup plan. Put a name and number in the window of the building. Do something to facilitate some communication with your customers. At the end of the day we are all paid via customer service. You are very fortunate to have a spectacular city "Sister Bay" to be the destination.
This is a horrid marina. The women's bathrooms was inaccessible. The Mens was absolutely filthy. The showers especially. The literature stated there would be someone there till 4pm. We arrived at 3:15 and no one around. We had to contact DOCAWA for internet code and bathroom code.
When arriving we were told to be on channel 9. No one was monitoring CH9. We called the marina via cell phone and no one answered. HUGE improvements are needed in STAFF and facility. This is a very busy marina. Don't know why it can't be better.
