As posted on the Welcum website? no need for proof of vacines?  So has anyone been down there since things have sorta reopened?

Love this Club! No problems with Covid restrictions, great selection of girls, mostly from Romania but a few Russians and others. Plenty of rooms and a secluded area right over the italian border. Hope to get back to the club soon.

Do they charge extra if you take a girl to your "overnight stay" hotel room for her?

Hi is this your favorite club?

When I was there, lots of girls.  Hotel was great, basic rooms but nice not to have to go anywhere else; Rooms were clean and I was able to find girls that were into what I wanted.

I visited Wellcum one week ago, right at the border with Italy, near Tarvisio. It's a fully fledged german-style FKK. A little extra cash got me bareback Greek with a 23 yo moldavian provider, CIA included (I know, I know, I was feeling adventurous).

Having said that, if travel to Europe, bringing your CDC vaccination card probably a good idea for good measure. It's very unlikely that they ask for it by now, but given how light it is...

what is the closest Airport?

Not sure. Vienna/Wien in Austria? I drove there from Italy. Pretty scenic view driving in the middle of the alps
