I stayed there in March/April for 4 nights. I thought it was fine. Our fridge was kind of noisy, but not enough that I felt like complaining. The walk was fine, I had a stroller for DD3. I actually kind of liked the walk back in the evenings because it was relaxing and peaceful. I thought the theme of the hotel was fun, and that's why I picked it. Would I stay there again? Probably not, just because I would like to get something a little closer. Next time I go, I'll be taking my younger DD and I would like to be able to take her back for naptime. I thought that Castle Inn was a tad too far for a midday break back to the room, so I didn't take DD back for naps. But that's just me.
Other comments:
There was a little convenience store in the hotel, we picked up a few things.
There was a small pool (in the middle of the parking lot) but we didn't use it. Looked like it would have been fine for a brief swim, but not somewhere that you would spend a few hours "lounging."
