Hey, it's my first time to costa rica. Just me and one other buddy are going and we are planning to be there for about 7-10 days in mid-March. We were originally thinking that we'd just rent a car and stay wherever, but I keep hearing that it's high tourist season and we might have some trouble finding a place to stay. We definitely don't want that, so where are some recommendations for what breaks to stay at for a March trip? Should we rent a car anyway and take day trips to waves? We are both in our mid-twenties and don't need things like ac, or a big hotel or anything like that, so long as we're safe. Any guidance would be helpful.

Thanks
