My daughter will be turning two in October. My other daughter is 4. I am having her party at a nearby park. There is a minature train there for the kids to ride and the shelter we reserved is next to the playground. This is the first party that we are having that is not just imediate family. The kids will range in age from babies to five years old. My question is do I need to plan other activities or will the train and playground be enough entertainment. I'm planning on a pull string pinata at the end of the party. Any opinions will be helpful. Thanks.
