I disagree that the ban would have affected tourism numbers, being that a very small percentage of tourists are from those 7 countries included in the ban, and I doubt a significant number of tourists from other places will cancel their plans to come here due to being against the ban.  However, I also disagree that tourism numbers will be affected by the so called "boycott".  The "boycott" is kind of like a bunch of Chihuahuas barking in a cage. In other words, a lot of noise but no action. Just a chance for people to vent. Trump, being the ego maniac that he is, may try to cut federal funds for Hawaii, but he doesn't pass the budget. Bottom line is I agree with Chin in challenging the ban, mainly due to constitutional reasons. We'll see how this plays out in the higher courts.
