Best/Favorite RV Resort

A few suggestions along I-10: Bella Terra, Pandion Ridge, both in Gulf Shores, AL
French Quarter Resort in downtown New Orleans
Buckhorn Lake Resort in Kerrville, TX
But like mentioned above a lot of campgrounds use the name Resort but are just plain campgrounds.

Our favorite RV park we went to for years is Fun Valley Family RV Resort. Resort in this case is a little misleading. It is not a high end/high dollar place. Resort refers more to what it has to offer. It is family oriented, but also has a lot of us old timers. We would take our 5er and our kids and grandkids stayed in cabins. It is large and strung out along a mile of the South Fork of the Rio Grand River in southern Colorado near Wolf Creek Pass. They have a restaurant, grocery, laundry, about 15 stocked trout ponds, paddleboats, tube floating on the river, miniature golf, real golf outings to nearby courses, horseback rides, street dances, C&W dancing in the barn, July 4th parades, etc. And short drive to Pagosa Springs, Creede, Great Sand Dunes, Cumbres & Toltec scenic steam railroad, etc. Or rent a jeep to go back country touring.

But it is a very active place. Some don't like it because there is a lot of activity, people out walking or bike riding, "train" taking people for rides around the park. It is a very old park and some of the sites are arranged somewhat haphazardly due to smaller size RVs in the old days.

We loved the place and had great time. Tons of memories of family vacations together.

Now for the disclaimer. We have not been since 2014 due to reduced travel. And the place sold about 5 years ago. New owners have done a lot of upgrades, but have also raised the prices over the very low prices we paid years ago. We have wanted to go back for years, but just have not been able to.

This place in Indio CA is pretty high-end.

I've never stayed in a RV park that I thought...this is perfect. I find something wrong with all of them, but I've never paid more than about $60. The Disney RV park in Florida is supposed to be nice but I have no desire to go there.
I haven't seen too many upscale joints in the places we travel. Maybe tourist traps like Gatlinburg.
I believe there are RV parks that only accept Class A motorhomes. You may want to do a search for more advice in the Class A forum here, or look in a forum for your brand of MH.
I'm guessing they are not on every corner though, so you may have to overnight in a normal park in between stays in a upscale park.
Maybe there's a secret list somewhere I haven't seen.

I guess I would define resort as a “full amenity” CG with paved roads and sites, nice clubhouse, pool(s), organized activities, etc. We realize that, depending on the season these kind of places are $80-$200 a night. However, having done my penance in my earlier life staying in tents and pop-ups on mosquito infested dirt sites, our later years will be spent glamping, not camping. I know this may come off sounding as rather elitist and not saying we would never stay in a CG with dirt roads but we tend to gravitate towards the higher end type places.

What is your definition of "resort" and how much are you willing to pay? "Resort" means different things to different people. That will help guide us.
