Are there any cultural things I should be aware of ?

Compared to other countries like the U.S.A., things move at a slower pace compared to most big cities in the U.S. or London.  Tardiness is expected and even coined as “Tico time” by expats.  You do have to be patient to live in Costa Rica.  Most expats go through culture shock while they become adjusted living the Costa Rican way of life.

Costa Ricans have long called themselves Ticos, in reference to the use of diminutives particular to Costa Rican speech.    

Personal space is a little shorter then what North Americans are used to, so don’t fret when you’re at line in the bank and you feel the person behind you is invading your personal space as you’re used to it
