I bought DD's at CVS. They had adults and kids. You can also order them online. Just do a search and pick a store. We used these for the first time a few weeks ago and they were great! We made sure to put them in 1/2 hour before dessent. DD, 6, was leery about putting anything in her ears but adjusted very to them. You can still hear pretty good. I already bought another set for our December trip.
