Kids Dig Sand Play Passes are a great way to give the gift of sand play to a loved one or to save money if your loved ones are Kids Dig frequent flyers. The more hours bought at once, the cheaper the hourly rate gets. If purchasing as a gift for a loved one, you can buy them in store or over the phone and Kids Dig will mail them to the recipient. Each pass has half hour increments to add up to the total time. They can be used over multiple visits for multiple kiddos until all the time is used up.
