Hi I want to take my children to the princess Diana memorial playground but I read recently that children over 12 aren’t allowed in the Diana memorial playground which I didn’t know before over 12 is classed as a “adult” and you can’t have more “adults” than children in a group, how does that work I have 4 kids age 8, 11, 13 and 14 will we not be allowed in with the older 2? Thanks
