All-inclusive resorts · Costa Rica

Hi there, I’m a 43-year-old woman planning to travel solo in early March. I’m not really into "commercial resorts," but if I find a place that fits my criteria, I might be interested. To add to the info in the title, I’m open to various activities, but ideally, it’d include snorkeling, hiking, dance (every evening if possible!), group tours, etc. I’d love to meet people (not necessarily a man—just people in general!). I’m not necessarily aiming for the cheapest resort, but since it’s spring break week and everything’s already pricier, 5-star options are probably out of the question. Thanks!
