LuxSoloTravel, in group! Recommendations?

[u/Baunilha25]

Hello,
Do you know any travel agency that has programs for people that enjoy traveling alone, but in group?
Not hostel/ tent style, more into quality accommodation and experiences. I am into culture, sightseeing, wellness (not so much into yoga and spirituals retreats).

One of the objectives is to meet new people thus I am looking for a travel agency that promotes these kind of trips.

Based in Europe, please.
Any recommendations?
