Might be quite a struggle if you have an issue with a few months of minimum commitment. We are regulars in a park north of Tampa. Five or six years ago, you could show up here, at the peak of the season, without a reservation, and stay as long as you want. Fast forward to Feb.2019 and 90% of current occupants had already put their deposits down for their same sites, in 2020. A few days ago, the office announced that next year was 100% booked full from Dec 1st to March 31st. Since our first bird season in 2014, we have not only seen a huge increase in demand in this area, but many parks are getting monthly rates that are 25-40% higher, and won't even discuss a reservation without a three month commitment. A few have waiting lists that are so long it's hardly worth bothering to get on them.
