We always used to make reservations ..... Just in case, you know. We are finishing up our 1st round-the-USA + 2 Provinces of Canada trip. We found you only need to have reservations on Holiday weekends. Otherwise, just show up. They have a spot for you.
Is that your experience?
Funny you should ask...My rule of thumb has been to never commit for fear of something coming up. It has worked for many years. Then it seemed that the campgrounds were filling up..so about 5 years ago we started making reservations during the winter months to capitalize on off season discounts that some of the area grounds offer. Well this year was a scrub for the whole season. Between weddings, funerals and child birth.. every single weekend was a scrub. I will never make advanced reservations again.
