    Great time. Hotel is nice. We wanted to switch rooms to get a better view and we were told we couldn't. That was kind of upsetting because I booked the room 6 months ago in December 2017

    Just a 24 hour stay and weather was cloudy and cool but room was comfortable and clean. Would stay again certainly if in the area.

    Bonnie castle is a great place to stay
    Came for a concert in Clayton and was told that Alex bay was the place to stay. Bonnie Castle provided solid accommodations as well as a fine bar and restaurant. The new owners seem to be making many improvements. The only problem is that the entire town closes down early. Perhaps I stayed early in the season, but by 10:30 the town and the hotel was in sleep mode.

    Disappointed in the thousand Islands
    Let me start by saying we got to the hotel we were all there was no elevator. I am temporarily disabled and I needed a room on the first floor. They told us they could give us a room with a Jacuzzi and then proceeded to tell us it would be 25 extra dollars. It was not something I would use I don’t even know if it worked but we were charged 25 extra dollars for it. Once we had a look around, we realized the Bonnie castle is a property whose time has most definitely passed. Sitting in a beautiful setting, this hotel was a complete disappointment for my wife and I on a recent overnight trip. The staff was not particularly friendly, and the hotel room was quite frankly in pretty rough shape. I’m not just talking about the the furniture being outdated—the walls were crumbling, we smelled mold in the cabinets,, and the floors were dirty. There was a jacuzzi tub we didn’t feel comfortable using. We would not stay there again. We included some pictures.
