Check-in from 15h (3 pm)
Check-out until 12h (noon) – beware of the time change (from summer to winter time) on October 26th!

Early check-in or late check-out can only be granted on prior request subject to room availability. An extra charge might apply.

Time zone

The time zone for Düsseldorf is Europe/Berlin (summer: UTC +2, winter UTC +1).

We are pleased to inform you that in the night from Saturday to Sunday during the IBD+ 2025 the clocks in Germany (& Europe) will change from summer to winter time adding a full hour that night.

At 3 o'clock in the night, the clocks will be set back one hour to 2 o'clock. No worries, this happens just once. Most computers, phones, watches etc. adjust automatically but you might want to double check in the morning and take this into account when setting your alarm for the morning…

Overall, this means that the IBD+ will last one hour longer than usual – without any extra charge 😉
