We are travelling to Paris for 3 nights in January with our two sons aged 11 and 8. Can anyone suggest fun/enjoyable things they might have done with their children or family members whilst in Paris? I have a list as long as my arm of places I want to visit but Im very aware I need to make it fun for them. I have booked a short river cruise and have tickets to go up the Montparnasse Tower as were staying very close to that!! All suggestions will be very gratefully received!
