Risk 01 · Wiesn
The 3-litre gate
Bags over 3 litres — bigger than 20 × 15 × 10 cm — are refused at every Theresienwiese entrance, and security measures them. A normal day pack does not get in. Luggage storage at P1/P5/P8/P10 is €5.

Risk 02 · Driving
The legal kit
Every German car must carry a warning triangle, an in-date first-aid kit and a hi-vis vest, and the low-emission zones need the green Umweltplakette. Rentals normally have all of it — but it is the driver who gets fined, so check the actual car.

Risk 03 · The baths
Last admission
Both baths close at 22:00 but they stop letting people in well before that — Friedrichsbad 19:00 (the circuit takes ~3h) and Caracalla 20:30. A 15:00 start is comfortable; a 19:30 arrival is a wasted trip.

Risk 04 · Money
Cash-only Germany
Most brauhäuser and every Wiesn beer queue take cash and nothing else. Hold €200 minimum, per person. Many public WCs want €0.50 in coins.
All trip
Risk 05 · Documents
The IDP
Every rental counter wants the International Driving Permit alongside the licence. $20 from AAA, in person, and it cannot be done from Germany. Drivers only — but if the named driver forgets it, the car does not move.
Before you fly
Risk 06 · Weather
Hamburg rain
Mid-September Hamburg runs ~20°C by day and 10°C at night, with grey and drizzle more often than not. Monday is the outdoor day and the Kiez night before it runs late — bring the shell.
Sun 13 – Mon 14 Sep
Risk 07 · Rental
Manual by default
German rentals are stick unless automatic was specified at booking. Check both confirmations now, not at the counter — one manual wagon means one driver does the whole trip. Pickups Tue 15 Sep, Stresemannstr. 364 at 08:30 and Hamburg City Centre at 09:00; both drop at Munich Hbf Thu 17 by 21:00.

Risk 08 · Rental
Two pickup branches
The wagons are at different Sixt offices, 30 minutes apart — Stresemannstr. 364 at 08:30 and Hamburg City Centre at 09:00 — and neither is at the hotel. Split into two teams before you go to bed Monday, agree who has which reference and which driver's IDP, and pick a rendezvous point on the A7 rather than trying to convoy out of St. Pauli at rush hour.
Tue 15 Sep · 08:00
Risk 09 · Beds
Wiesn surge
Munich hotels run 2–3× on opening weekend and the trains cap out on the Saturday. Munich is booked. Köln is booked — KONCEPT, Altstadt-Süd — so every bed on the trip is locked.

Risk 10 · The drive
Tuesday is 600 km
Hamburg 08:30, Autostadt 11:30–15:00, Köln around 19:00. Six hours behind the wheel with a museum in the middle. Rotate the sober DD in each wagon and take a real rest stop — this is the longest driving day of the trip.
