“Me gustó muchísimo mucha limpieza muy trankilo”

Ivis Ybargollin M 5 · Jul 2026 · Campspot

“Great location, great staff and a really nice community. The sites are a good size. The event planner is awesome. Her enthusiasm at events are a lot of fun. Great stay again at a Sun Outdoor Rv Resort. This is our third stay and it keeps getting better!”

Joseph M 5 · Mar 2026 · Campspot

“Wish we would have been able to stay longer. We were there one day went to the office my paperwork was ready. Was shown to my site and helped hooked up. Shown where the bathroom was and where to watch the sunset…”
