Hi Franjo,
Congratulations for your choice, Samya is always worth a visit.
There are no special days and differences wed/thu.
What concerns Bernd's Hof (abberviated from the address: Schieferhof 28), it is quite a different experience. Where Samya is a new building and installations, the hof is a private house in a village built in the 60s, it has two floors, and especially the lower floor or basement (with a bar, some couches and a few rooms) has a very cozy atmpsophere with a lot of laughter among the guests and girls. As it is absoluetly usual that the girls begin with the blowjob in public, you should not be shy that other customers can follow the beginning of the "action". You must try it to judge.
The Hof is not situated very centrally in the village of Hennef-Lichtenberg, if you don't drive a car, you should go by train to Hennef station and take a taxi there (instead of paying some 80 euros from somewhere in Cologne). The Hof cooperates with a hotel in the neighbourhood (Reuters, Hennef-Lichtenberg) which does also the catering of the buffet of the Hof.
You may be a bit mislead by the kind of reporting on Bernd's, as even when it is really full of customers you will not feel bored (you might have to wait for a room to be free, but this will only mean that the "warming-up-time" with the girl you choose is extended
