Planning a family holiday can be quite stressful. When holidaying with children you may need to plan activities ahead of time and think about how you can keep them occupied. You may not be able to stay sunbathing or in the pool all day if it is very hot as there is a high risk of sun damage, especially for children as they have delicate skin.
If your children are quite different in age then you will need to think of things that you can do that will suit all of them. It may be something that is suitable for a 12 year old is not suitable for a five year old.
If there are two adults going it may be that for one or two days of the holiday you do separate activities that each child will enjoy. You could also try and find activities that vary dependant on ages such as a rock climbing centre which has a toddler wall and a teenage wall.
Research shows that the majority of children enjoy spending time on the beach when on holiday regardless of their age. This is a cheap option but ensure that you have a parasol or a shade area where you can avoid the sun during the hottest part of the day.
