I read that Nordic MEPs are trying to make its fellow (male) members of the European Parliament to set a good example by not using hotels that do not have an explicit policy against prostitution. 37 MEPs (out of 700 something) signed a letter addressed to the Parliament President stating "[We] strongly propose that the EU parliament without delay follow the Nordic Council* and decide that the EU parliament only use hotels that issue a guarantee that the hotel is not involved in the sex trade, and that all staff have written guidelines on this issue". The move is to particularly target hotels that turn a blind eye to what happens or even encourage it.
* The Nordic Council adopted a policy on prostitution and hotels in 2006.
