I checked a few of the "Unfriendly" and this is typical from what I saw:
The location is excellent and the park is clean. Very noisy with freeway right next to it. The only real drawback and what turned me off was the managements very strict attitude toward the guests, the above average amount of nosey "park" gossip often initiated by the management. I have also heard the staff use horrible language while chastising guests for minor infractions with the threat of expulsion at their discretion if the guest took offense or defended themselves verbally. Would be a fantastic place if it were run with a friendlier and more businesslike staff.
