The check-in waiting line is 20-30 mintues. So I chose to self express check-in. The express check-in is not working. But the hotel does not put a note. So I had to stupidly wait for "the room is not ready. Will notify you by email or check in later" for 30 mintues. Then I called the hotel hotline waste my 10 mintues but they never figure out. Then I grab a chance to ask a manager to know the self check-in is not working that I have to wait for the long line. Terrible check in experience.
