Travel
Fly in/out of Juan Santamaria Airport in Costa Rica.
Ground transportation options are abundant, we suggest Interbus.
We recommend that you stay at Selina in La Fortuna, Costa Rica. That is where the newlyweds will stay and it will be the central meeting point for all. However, La Fortuna is a small town, there are many lodging options within walking distance, you should feel free to pick any you like.
