We just returned from palm springs and like you had never been there. We reserved 1 night at Catlina RV Spa and Resort and ended up staying 4 nights and unfortunately had to leave. We loved it, people in park and staff were extremely friendly. 2 pools, 2 hot tubs, nice showers and restrooms if needed. 6+ pickle ball courts and even free putt putt! Also they advertise at $45/night, but with passport America it is half off. We signed up since it is only $40/year. I believe they said you can stay 2 weeks using passport America pricing.
This is another thread running about palm springs as well that has a lot of recommendations as well.
