We are aware that it might be a bit tricky to get accomodation for that weekend. If you are comfortable with being hosted and in need for hosting, you can get in touch with the local swing dance community, a few of the Stuttgart swing dancers might be able and willing to host. The community is connected via Facebook (Group "Swinging Stuttgart") and over a Signal-Group (this is the Invite-Link). So you can try to connect with people through these 2 options, we would recommend the Signal-Group.
It is probably clear anyway, but be aware that we try our best to help also in this matter, but we cannot take any responsibility for the outcome. You are responsible for yourself in making up a suitable hosting arrangement for either side. Good luck :-)!
