Swinging Germany for the first time, advice pls

I'm going to Golden Lions, Wellness Day on Sunday afternoon. I've been swinging for years, mostly in Spain, but never in Germany. Any advice, thoughts, etc?

I'm not going with my swinging partner, its just me, myself and I.

Dates to ☆ 🔴 ☆ WELLNESS DAY ☆ 🔴 ☆ Massageverlosung

The place looks cool and chilled out, and it looks like food is provided, so that´s something new too.
