for those arriving early and are in Cologne tomorrow:
For sight seeing we meet at about 15:30 o'clock in the hotel lobby.
Then we walk to the cathedral where our tour starts at 16 o'clock.
We meet in the lobby at 18 o'clock to meet and greet. Then about 18:30 o'clock we can walk to the old market square for a nice restaurant.
Dinner is planned for about 19 o'clock. If you are late, you can always text me to ask where we are.
