I wonder what you will do OP if in years to come one of your children struggles with life and has problems? Will you insist they are only given exactly the same as their siblings even though they may need more? Or will you, like most parents meet that child's needs, effectively making them the favourite just as your in-laws have.
It's silly and useless to behave as you are doing to your in-laws. Will they change? Of course not. Try just accepting they are doing their best just as most of us do. Then make your decisions without resentment focussing on what is best for your children and not how you feel about your in-laws.
I do wonder why you won't permit "fun" sessions are you perhaps afraid your children might enjoy time with your in-laws?
