Does this mean that if I own a credit card for the purpose of being able to charge stuff on vacations, I will be screwed? - because, after the first day of spending, my card will be suspended owing to an 'atypical pattern'? - and they can't get a confirmation on the charges by calling my home address, naturally, because I will be on vacation?
