Me and DH work so my 2 DC spend a lot of school holidays in holiday clubs. The majority of their friends have at least one parent who is always at home in the holidays so they are always having friends round, going out for trips with other friends etc.
My DC don't do any of that as on the few days we are at home, I want to spend time with them as a family.
I know they are gaining invaluable social skills by mixing with different children and they both love the clubs they go to. I just feel sad that it means they miss out on social time with their mates
