My personal opinion that there is no chance that effects of any kind of sanctions can be seen so fast. Maybe I am wrong, but I believe that it is excuse for shady business practice that I've already seen so many times with local tour operators and scammed people.
And ask Montenegro that supported "sanctions" on Russia, how their season this years looks like. Completely empty, Russians went to other destinations to spend money. Planet is huge enough and European idiots that are imposing sanctions will take most damage , while US is applauding to their stupidity. Winter is coming.
Meanwhile in Russia:
