I've been to Algonquin Trails three or four times now, and I'm a bit dismayed by the poor reviews.
The owners, Dan and Laura are fantastic people. If you treat them with respect, you will get fantastic treatment in return. Frankly, I love the fact that they don't tolerate disrespectful campers because I enjoy camping in a quiet family atmosphere.
Also, you have to keep in mind that you are visiting a relatively small, family run establishment. They have to keep an eye on the bottom line to get by. If something isn't cost effective for them to offer, they probably won't offer it. Nor will they have the free time to staff the office and store like it's a 7-11.
On my first visit to the park, we only spent two days there until our reservation in Algonquin Park was freed up. After moving on to Algonquin Park, we wished that we had stayed with Dan and Laura instead! On subsequent trips to the area, we stay at Algonquin Trails, and visit the Park during the day.
I was a brand new RV owner (and new to towing, and more importantly reversing while towing) and Dan took the time to give me some helpful tips and useful advice.
Another refreshing thing about the campground itself is that you don't have a situation where the seasonal campers act superior to the short term visitors. This is a fairly common dynamic at many campgrounds, and it's nice to not have to tolerate it at Algonquin Trails.
I suspect that many of the negative reviews come from people who didn't respect Dan and Laura, or their rules for the campground. Everyone thinks that they are a courteous camper, when in reality, very few are. Some of those people should stay at a campground where the rules are poorly enforced, and they would appreciate the environment at Algonquin Trials a little more. ;-)
In terms of an enjoyable camping experience, I rate Algonquin Trails very highly and I've stayed at multi-million dollar campgrounds like Disney's Fort Wilderness.
