My DSs belong to a swimming club. They use the town baths which a fantastic new facility we are lucky to have. ATM their session is 6:30-7:30 pm. For the next three weeks one of the (foreign) Olympic swim teams will be using the pool for several hours a day, which means it will be closed to the public and the club session has been moved to 7:30-8:30pm.
Usually my DSs are in bed by 8pm and lights out 8:30 so swimming night is already a late one for them. DS2 particularly needs his sleep, I really don't think 9:30 to bed on a school night is a good idea for either of them.
But, I have paid for the sessions whether they use them or not and if they don't go, that will make 5 weeks away from the club as we're on holiday for the first two weeks the sessions are back to normal.
They're 9 & 11. What would you do?
