Does anyone know of any alternatives to Mark Warner /Nielson but in Northern Europe? I’m looking for similar set up (organised activities, kids clubs divided by age) but not in Greece etc as it’s too hot in the Summer which is when I’m looking to go. I’m a single parent so this type of holiday is ideal - my son is more likely to try new things with kids his own age and I’m not about to take him canoeing or sailing:)
