Never been by Rincon West, but stayed at Rincon East for 5 days in Sept. Didn't do any of their offerings, except swimming in the pool.
Our daughter lives a block or two from the park.
The restroom & showers were clean by the pool, but didn't see the exercise room or any others. We had the pool mainly to ourselves. Had cable. A quiet park. Not real busy this time of year. A lot of park models & setup RVs, most seemed empty, but some with people. A very large place, did see but a small area. Staff were friendly as well guests.
LadyHawk, Our Five YO Grandson & I got to go swimming each evening we were there in the pool at the park. Our Daughter did each day but one. She wanted to get food ready for supper. Her Hubby was able to go swimming twice as well, the first day & the last. We all had a great time.
