When we had foster children my sister and I took them on a day trip every Tuesday all summer. It was a lot of fun and something to look forward to. It was easier on us than taking them on an extended vacation. Any change in routine was difficult.
Now that that season of our life is over we have missed the fun times we had together and decided that this summer we would do summer Tuesdays just for us. Both of our husbands are working all summer and that leaves us some time to be sisters together without driving them nuts!
