Many things are a matter of expectations. But I understand your frustration in "truth in advertising" issues.
Price is a relative thing. I've seen nightly prices has high as $250 a night with a 3 night min. near New Orleans for Mardi Gras and over a $100 a night for FL waterfront.
As for WIFI I understand your frustration but on the other hand I know it's very hard and expensive to build a system to cover the area of a campground to handle the peak flows of traffic and no dead spots. At our current "resort/CG" we are parked maybe 50' from they WIFI antenna and it's still slow and spotty service. On the weekends it's pretty much useless, so we just use the hotspot on my phone. Providing WIFI in an area like a house or a restaurant is one thing but covering several acres is another. I don't expect much from "free WIFI". If I paid for it, I'd expect more.
As for the size of sites I can get some idea from looking at the photos of activities posted and google earth can give you a feel. Different people have different expectation on lot size. Some CG's offer larger sites for a premium. Since the infrastructure is expensive to install there is a tendency to group the sites together. If all you want is some power, the sites can be further apart. When you add water and have to stay below frost lines the cost goes up. When you add sewer and grades for drainage the price goes even higher. We have been at nice CG's in the east that the cost to install sewer was cost prohibitive due to the rocky terrain. Commercial CG is there to make money. If I want a large lot, I guess I'd look for an area with low land prices of where the state or fed's owned the land. Some place like Liberty Harbor Marina & RV Park (
http://libertyharborrv.com/ ) is simply a parking lots near major attraction in this case NYC and you are paying for location at $80 a night.
I realize we have not traveled as much as some members but so far we have stayed at places that live up to our expectations. Maybe we have been lucky.
Would it be reasonable to say all sites should accommodate a 45' rig and tow vehicle?
Should all CG's have 14' clearance?
Should all the access roads accommodate the above 45' RV and tow vehicle both in road width, height and turn radius.
I have come to expect that my rig just won't fit in some places and I'm ok with that. I understand that I won't fit in many State and Federal CG's and I'm OK with that. I don't fit in Chain o Lakes park near my home both because they won't trim the trees and the sites are too small. It would be nice if some of these place accommodated my wants/needs but what is a priority to me is probably not a priority to someone else.
As someone who has family get together at a CG. I like having 4 generations around the campfire. I guess I'm guilty of inviting all my relatives for dinner. We also paid $5 a head to get the extra people into the CG for the day.
