make sure you go up the eiffel tower. the view is amazing even from the first viewing floor (thats as far as i went)
as foreurodisney, depends on how many days you are going to paris for because you need a full day for disneyland. when we went to paris, 2 of the group went out to e.d, went early and back late. as we only went for 2 nights they missed out on a lot of the sights in paris. they loved it though.
dont feel guilty about going without the kids, sure dont you deserve a little fun sometimes without them. 😆
