27th April 2016... That's when I went... I remember because it was the best day of the year!!! You're going to absolutely love it. Plan ahead and make sure you get a tour of all 3 (BMW Museum, BMW factory, and BMW Welt) BMW Welt is free to have a poke around anyway but I definitely recommend the tour of all 3.

I didn't rent anything nice as we were on a budget since we were "travelling" rather than "on holidays" but Mark said he rented an F13 M6 which was fun on the autobahn he'll probably chime in with more info.

With regards to nightlife in the city, you're essentially in the Middle East, so think shisha/hooka, falafel etc you may also want to learn Arabic before heading over
