The airport is located in Alajuela about 20 minutes from San Jose. You can also arrive in San Jose by bus: there are many buses that travel between San Jose and cities such as Panama City in Panama and Managua in Nicaragua. You can travel by car from North America: it can be an exciting but difficult trip because of crime, violence, corruption at border crossings, and problems with visa formalities.

There are several ways that you can get from the airport into the center of San Jose. There are car rental agency booths at the airport if you choose to drive a car to get to San Jose: however, driving is not recommended as the roads are in poor quality and road signs can be very confusing. There are public buses that are very inexpensive: they pass the airport every ten minutes. There are also red TUASA and yellow Station Wagon buses: these both stop directly in front of the terminal. If you have a lot of luggage you will probably want to use a taxi. Photo: Mihai Bogdan Lazar/Fotolia

San Jose is a great place for a wedding: it is an easy process and there are many choices for wedding venues. All you need is your current passport: you’ll fill in some basic information on some forms that are provided; and you need two witnesses at the ceremony. Most foreigners get married in a civil ceremony officiated by a local lawyer. The lawyer records the marriage and then you get your official marriage license. After this, most people have a second wedding at one of the many fantastic locations in and around San Jose such as the Real Intercontinental, the Costa Rica Marriott, the Crowne Plaza Hotel Corobici, Villa Blanca Cloud Forest Hotel, and more.
