This campground will not work for people wanting a one night stay because there are no pull through sites and each campsite would require disconnecting the trailer or tow car to fit in the site. 
I checked out their website and it states they only have monthly rentals so this is not a camping RV park. 
About 1/3 of the campsites are adjacent to the Rogue river and all of the others have a view of the river. The Wi-Fi is acceptable, they have cable TV, full hook ups and well maintained property.
The other campers are mostly travelers and respectful. Nothing negative to experience.
The campsites are all surrounded by trees which is beautiful. There are cabins, tent sites and full hookup RV sites. The pool and hot spa pool are well maintained. They have an afternoon snack stand with corn dogs, funnel cake and more. Close to lots of beaches and trails.
Only reasons I don’t give 5 stars is -
the RV sites have connections in center of site which is difficult for hoses and cords.
Some RV sites are very uneven and sloped making it hard to be level.
Campground Wi-Fi speed is very minimal.
The camp manager was very helpful and very friendly and the people staying here are polite and quiet. It does seem like many of them are full-time residents. The creek that is adjacent to the campground looks polluted and ugly but the campsites were adequate with lots of tree cover. Not great if you’re trying to do a satellite TV but we only stayed one night. Wi-Fi is very slow as in 1 Meg speed.
This is my first time using a thousand trails membership so I didn’t know what to expect. The overall campground is nice with almost all of the sites being surrounded by trees or a view of the bay. But it was disappointing to find that the few sites that have a sewer connection were all taken and no way to know this in advance. The Wi-Fi they have is only at the recreation building so that amenity should not have been listed on their website.  About 20% of the campsites were being occupied by people who seem to be living there year-round with questionable RVs and lots of junk around their site. This diminished the overall nice setting of the campground.
This resort is a great place for RVs. It is across the street from a shopping center that includes Costco. About 20 miles south of Portland along I-5 freeway with easy access. 
The beach is about a quarter mile away from each campsite and whether one uses an RV or tent, there’s not much else to do here then take the trail to the beach. They have restrooms and fire pits and picnic tables and they sell firewood. But all of the campsites are laid out like a parking lot with no real ambience around. Very nearby there is a railroad track and freeway which provides a distraction from a little bit nature nearby. 
I have stayed at this RV park several times as a stop over for the night. It’s not the kind of place I would want to stay at much longer but it does have all the power and water connections that one needs for an RV. Most of the sites I have stayed at have the connections at the center of the site which makes it a little awkward but most of their sites are pull through. The park is adjacent to an older mobile home park but if one stays near the front of the RV park you won’t even notice this. The rate we paid was about $45 a night and we thought it was worth it versus pulling in to the nearby Anderson’s Pea soup parking lot and squatting there.
I have stayed here several times as a waypoint on my travels between California to Washington.  It is a nice safe quiet park that has many pull through spaces for RVs spending the night.  I have used their website to reserve a space and then pick up the paperwork outside the door of their office.  so far I haven’t met any of the owners or staff but all the hook ups work and I believe they have Wi-Fi as well. 
We stayed at this resort as a guest of a member and though it is nice it is not available to the general public. 
This RV park is actually a resort in itself as it has three swimming pools, a large soccer field, basketball hoops, bocce ball courts, water splash area for kids, etc. it also has a small outdoor restaurant that serves pizza and chicken wings and a full-service General store. Lots of stylized cabins are also available. Only about 3 miles from Solvang. The only negative is it can be quite expensive but I guess supply and demand takes care of that. 
Comments are similar to others who posted here - pictures may add some detail. Only some sites are suitable for RVs with limited hook ups.
