Wow – hope you like it! Been a few times but we last stopped there on the way home in 2012 – was awful traffic Ulm-Stuttgart so we only managed to squeeze a couple of hours dash round museum (open until 7pm on a weekend so was really quiet and got the Jumbo / Submarine etc to ourselves). There is a big metal tube slide down from the Jumbo and a few other planes 🙂
Breakfast was good in the hotel. Speyer city centre is easy walking distance – felt like there were millions of ice cream cafes open in the evening but we eventually found an Italian tucked down a side street for pizza.
Sister muesum at Sinsheim 40km down the road is also good (can climb into Concorde and Tupolev “Concordeski” at jaunty angles on the roof). Makes UK museum efforts to exhibit Concorde look a bit lame…..
We’re currently looking at West Austria / Switzerland combo.
