I’m making this trip next week so thanks for talking through it. Thankfully I made sure my DB train journey included the bus, when doing the journey search you have to select Europa Park/Rust NOT Ringsheim/Europa Park, then the 7231 is added to the planner. Your second mistake assuming the driver wasn’t ready yet I would probably have made too so thanks! If people are waiting there I’ll know it’s cos it’s hot! You said you wasted 15mins, was it not an hour? I was pretty sure that bus is every hour not every 15mins..
