The Managua Intercontinental sits on a small hill with a nice view of the city and lake. It's a 30 minute shuttle ride to the hotel that highlights the less scenic areas of the city. We had a nice dinner at Antijitos, across the street from the hotel. Also, there's a mall nearby, with American fast food and good donuts.
It's a 40-60 minute white knuckle taxi ride to the Caracas Intercontinental. Traffic was incredibly busy, and the fumes were terrific. If your eyes aren't red from the travel, they will be when you exit that very long tunnel through the mountain. We ate at the hotel restaurants. Good food, but no bargains.
