CIS Qualifier for King’s Bounty 2017.

now you're talking about May 13th

In the first vote for the city to host the event, May 13th was announced as the departure day.
If May 13th is the gaming day, and May 14th is the departure day, then we need to understand that everyone will have to go to work on May 15th...
Although, considering the conference hall that's available for 10 hours... even 10 gaming days wouldn't be enough.
