How dare they charge this amount a night. Plumbing fixtures loose. No amenities. Wasnt aware of a micro wave availabe until final morning. Additional coffee in lobby area not working. Take Resort out of the title. They have nothing.other than the pool and jacuzzi. A resort is self contained. Along with activities and entertainment I saved for 2 months for this.

For the price of a nights stay, you’d think they would invest some more money into the hotel! Rooms were clean, but old and outdated. Just as outdated as the grounds surrounding it! The restaurant was understaffed. The grounds yet again were in need of some TLC!

The room was like a motel in the 1970s. No carafe for the in room coffee maker had no carafe. The seat on the toilet seat had only one bolt holding it to the bowl. It literally spun around. Laminate counters felt some what cruddie. Clean but really, really dated! Hard to find on a route that winds around a working boat yard. Beautiful location across from Boldt Castle, but too expensive for what we got.
