Updated review: seems the new owners are intent on driving away loyal return guests. We come to Prosser twice a year but were told we cannot make our reservations for June of next year for reasons unclear ( it sounds like spaces are being held for full time residents which will definitely change the dynamic of the park). New wine room is cute. Office staff are doing their best to navigate the poor choices made by new owners, but you can tell they are weary from having to explain it all to the guests. The grounds are green and clean. The pool was closed (see previous reviews) - seems to be an ongoing thing. We have reservations for September (made last year) and will be back - although it may be the last time (which is a super big bummer).
