On some days as a nanny over the summer, the parents would give me some money for a special excursion with the kids. We could go wherever we decided to spend the money.
I know growing up the days where we could do something special was always the greatest. My favorite thing to do on these day was to go play mini golf! Other days we would simply go to get ice cream or frozen yogurt, which was always a nice treat.
There are tons of great things to do for a nice excursion. We could go bowling, ice skating, see a movie, paddle boating in the Tidal Basin in DC or Kayaking on the Potomac. These are just the ideas we a came up with this past summer.
Let me know what other ideas you have!
