We will be flying into Costa Rica on airline buddy passes which means that if we can get into LIR vs SJO we will take LIR and vice versa. In addition, its the same with leaving as we wont know until 24 hours before if we can get LIR or SJO to fly out. So which car rental company would be better to choose who has locations in/near both airports and can take a change in drop location within a few days prior to leaving? Also, we could get out of Managua Nicaragua if we decide to get up that far, so any issue with returning in Nicaragua???
