Question Planning a 10-Day Anniversary Trip to Costa Rica

Hello fellow travelers, My wife and I are planning our anniversary trip and decided to visit Costa Rica. We have a total of 10 days from Early to Mid June of 2025 and would like to see as much as possible. As much as I would love to see the entire country, I understand that 10 days is just not enough, because there are so many interesting places in such a small country. I have spent the last few days watching YouTube videos and reading blogs, but I'm still overwhelmed by the options. Should we focus on the beaches, the rainforests, or try to balance both? Also, any recommendations for must-visit places or hidden gems would be greatly appreciated. Looking forward to your suggestions!
