When we take our trip to Nicaragua , we will arrive in Managua airport around 930pm. Is Managua safe these days? We want to get to Leon as soon as possible and thinking about renting a car. Should we wait till the morning to rent a car or just rent a car when we get there to get the heck out of Managua? Please advise. We like traveling but we want to be smart travelers and like to be aware of safety issues. Thanks.
