Not that it matters at the moment since Dec 24th 2021 through Jan 9 2022 are already booked with regards to WV, but Conrad contact told me that there were 7 night minimums instituted during that timeframe to book WV's. For dates outside of that, there are no minimums night restrictions to book WVs. With that being said - take that with a grain of salt as obviously other posters have mentioned that they could only find availability at a week at at time along with I had to ask a couple of times about the minimum nights to the same person - so I'm not sure if there are some communication errors.
