Traveling for two weeks in Costa Rica on a mid-range budget will cost you around $2,000 - $4,000, including accommodation, meals, day trips, and car rental. In general, a hotel will cost you anywhere between $50 and $150 (hostels cost as low as $10 a night), a meal costs between $15 and $30 per person, and transportation can be pretty expensive so you'll want to budget around $200 per person per week. Lastly, you should plan between $100 and $200 per person per week for entrance fees and day tours. Of course, the more people in your group, the cheaper it'll get, so that's another factor to consider.
