If you need, your driver can wait for you at the airport with a sign with your name on to welcome you. Don't worry if your flight is delayed as your driver will still be waiting for you, they just need your flight information to check at what time you will be arriving at San Jose airport in Costa Rica.
If you already are at your hotel, your driver will pick you up at your hotel. Just pick the time and your driver will be there to take you to Samara Beach.
All units are very comfortable with air conditioning and an English-speaking driver. If you need to stop for anything along the way just let your driver know and they will do it with pleasure.
