1. Don’t load at home

Hello, please help me: drive next week to Holland (West Kappelle) and want to charge at a public charging station near the hotel for the return journey. In the me app I entered the place and also found a station where I can load AC (do not need a quick charge). Before I searched for the station, I clicked on the buttons available in the app and Mercedes me App and MBUX. Question: does this mean that I can pay at this station with Wercedes-me Charge? Another question: can you choose between AC and DC at charging stations, or is there only one or the other?
