Nicaragua is a good country to travel with kids. I have never been to Corn Islands but I would never travel by boat/bus back from there to Managua. We always made bus trips from about two to three hours (by microbus or regular), stayed a few days and continued to an other place. A nice place to stay with children is absolutely Isla Ometepe Charco Verde or Finca Playa Venecia. There is a near Nature Reserve where you can see Howler Monkeys and the beach is good for children in that age. Visist the Water Hole Ojo de Agua with natural fresh water swimming pools.
I spent several times in Las Peñitas at Hotel Barca de Oro just in front of the Laguna, where children can swim. When you stay in Granada do a day or overnight trip to Laguna de Apoyo, fresh clear water and the kids will love the kajaks.
I have never been to upscale hotels in Nicaragua and I don’t know if they propose children activities, never needed it. I don’t supose that there are special children friendly things in Nicaragua, but in all Nicaragua children are welcome and you have to find your way. I supose it is not the first time you travel with your kids and you know what you expect. I love Nicaragua, enjoy it.
