The Arizonian RV Resort is a great long or short term RV park (including park model homes) designed for a 55+ community. My folks live here during the winter and I love to visit as the Arizonian has activities all the time for guests and members. Everything from a pool/hot tub, laundry and gym to concerts, poker nights, gourd painting, crochet/knitting and quilting clubs. They also have an RC plane landing strip, an RC car track (and cool race events), a golf course, access to public lands for ATV/UTVing, an ATV/UTV wash and more. Pets are allowed in part of the park and rent is reasonable for a week/month/year.
The weather is great during the winter months (cant speak to summer). And there is plenty to do outside of the park that is within driving distance.
