I was listening to Extra History’s Seminal Tragedy story about the time before the explosion of the cataclysmic First World War. They (the extra history guys) recounted that Kaiser Whilhem took a vacation on a boat for 3 weeks when Austria and Serbia were still trying not to go to war . Where did the Kaiser go ? What was Kaiser Whilhem doing ? Fishing ? Drinking ? Planning ?
The Kaiser would annually embark on a tour of the Baltic, aboard his pleasure yacht the Hohenzollern.
While the crisis between Austria and Serbia proceeded slowly the Germans were anxious to prevent the war from growing to become the global conflict (which it eventually did), following a policy of 'localisation' of the conflict to the Balkans.
A key aspect of maintaining this policy of localisation, was preventing the crisis from escalating and so, it was decided that any change from normal could escalate the crisis.
Therefore, Chancellor Bethmann-Hollwegg encouraged the Kaiser to take his usual tour of the Baltic and many other senior commanders either extended their holidays (Helmut von Moltke, Alfred von Tirpitz, Hugo von Pohl) while Count Waldersee and Erich von Falkenhayn soon both also took time off.
These holidays seem to have been taken because the high command genuinely still believed the conflict could be localised and out of recognition that nothing could be done until Vienna took action.
As for the Kaiser, he likely spent his time on the cruise throwing banquets, meeting locals in the ports he stopped off at and studying archaeology. I haven't been able to find anything actually detailing what his itinerary was unfortunately.
