To be honest I would do all or none at that stage. It is tricky and expensive but having been on the receiving end of no invite it was pretty gutting to hear everyone else carry on about it. I agree that when the kids are bigger and in a huge group then it is easier to go with the kids friends where as it is more about the adults in MG. It does depend on the dynamics of the group and the split too - if only one or 2 are excluded than that is a bit difficult. Each to their own tho!!!
