School holidays or not, when the kids have to play, it's best to take them out of the house once in a while. While it's a no-brainer to allow the kids more screen time to keep them occupied, it's a slippery slope you don't want to start on. Instead of keeping them homebound, let them run riot in an indoor playground. Rock climbing, trampoline arenas and obstacle courses sign them for a day of madness (and fitness) at one of these outdoor playgrounds.
