Hello! I'm going to be leaving on a flight that departs SJO at 2 am. I'll be taking a bus that will get in around 9 pm the previous night. Will they allow me to hang out at the airport from 9pm until boarding time, or will I have to make other arrangements? Will anything be open at that time? I'd rather not have to pay to get to a hotel/hostel for just a few hours. Thanks for any info!
