I got a new Ipad for Christmas and have an older Ipad and an Iphone 6S. I want them all to have the same password. Is that possible? And do I need to bring all of them to the store? Carol W.

Agree with Victor. Otherwise, make an appointment with the store or call them for help.

The questions that are asked in Google maps are directed to individuals who have visited the venue not to the store itself. That said, and noting that I'm more an Android user than an iOS one, assuming that you are talking about logging in to the iTunes store with the same ID and password from all devices I believe the answer is yes you can and you don't need to go to the store.
