What should I do ?

Okay ladies , I have a issue ! My sister was possed to have her baby in September .. well she’s going in labor as we speak ! I live 24 hours away , my husband and I live in Kansas .. he is getting ready to deploy next month ! Should I wait out the trip , save money and spend time with husband until he leave and then go see sister and baby . . Or should I go see sister and baby for two weeks come back home and spend the rest of the week and a half with husband .. ?
