most important is: book asq at hotel directly. Mostly you get a confirmation of your request and information how to pay. And what paperwork they expect. Some hotels have regular guests and asq guests. In separate levels of the hotel. Have a look at your booking . Did it mention asq?
that is sometimes a problem at airports. The checkin people are not always up to date with the rules.Maybe almost impossible, get travellers to all over the world. I have had same kind of problems but asking fotr the supervisor is sometimes the easiest way\ to solve the problem.
