Harrah's Rincon allows RV Parking on the lot to the South of the Casino. I checked with security and they have no problem. In fact they encourage it. I was told we could bring a group if we called first. We stay at the Woods Valley RV Park in Valley Center. It is close to the Valley View, Harrah's, and the Puma. Harrah's and the Puma have level lots and lots of space. Both are accommodating to guests. The buffet is good at the Harrah's and there are a large assortment of slots. It is a little tight however. This is a beautiful area. Lots of Citrus and the hills are beautiful. Some have recently burned near the Valley View and Harrah's but are recovering nicely.
