I plan on taking a 2 week adventure to California in late April to May for about two weeks. Stopping in various spots on the way, some spots a little longer then others to check out the national parks and do some hiking. I plan on stopping all over Northern/Central/Southern California especially on the coast same with Oregon, and Washington. I was wondering if I should book ahead for camping spots (Me and my friends will be tenting a long the way) and book 7 spots spread across the trip and just airbnb or hotel day of if we cant find any available camping areas. I would like not to book to far ahead and book pretty much the trip because there may be areas that we would like to stay at for a extra day or so. Any knowledge of drop in availability or planning would be greatly appreciated!
