Traditionally, My husband, the 3 kids, and I have split Easter Sunday amongst our family. My side usually goes to the park around noon, has a picnic, and all of the kids hunt for eggs, etc. We try to do it early because a relative works in the afternoon. We usually go over to his parent's house in the afternoon and have dinner and stay the entire evening. This year things have changed. My husband's sister and her husband decided to go on a trip and have my In-laws watch their daughter for a week. After their trip they fly in Easter Sunday at 6am, plan to stay a little during the day, and then all of them have to be at the airport by 5pm to go back home. My MIL isn't planning anything Easter-related for the day. It's just a simple lunch and visiting. The kids will probably be bored and watching TV in the back room. They live in an active adult community and it's all rocks and desert plants. There's not an outside area to play in. MIL doesn't want it combined. What do we do?
