We are flying into Managua late at night and leaving the next day for Ometepe. The hotel operator in Ometepe suggested the 9:30 am ferry and said, we would be more comfortable on that ferry. We are worried about taking such an early ferry when we have never been to Nicaragua before and don't know how long it will take to get there. We will have a rental car. Is there any reason not to take the 2:30 ferry? How long will it take to get to the ferry at St. Jorge from Managua?
