I'm thinking now about what the economic impact upon Las Vegas will be. Tourism is THE industry there, and without tourism, the economy will be in the toilet.. Tourists who were in Vegas when this happened (but not necessarily at the show) were saying they were cutting their vacations short and heading home. One couple which had been married in Vegas over the weekend said they were headed to a beach in California for the remainder of their honeymoon. I would imagine that some tourists with plans to visit Vegas might be rethinking their vacations. People might be thinking the city is too dangerous.
On the other hand, if tourists decide to stay away, anyone brave enough to venture to Vegas might be able to take advantage of some deep discounts . Shortly before 9/11, a friend and I had made plans to head to Vegas that October. Although my friend was uneasy about flying, I convinced her to go and we had a wonderful time. We had already reserved a basic room at the Tropicana, but when we checked in, I asked the clerk what it would cost to upgrade. She gave us a much more luxurious room for the same price as the basic room we had reserved. Shows and meals were discounted. I budgeted a certain amount of money for the trip, and even after playing the slots, meals, shows, shopping and what not, I spent maybe half of what I had budgeted.
An incident like this could be a boon to travelers, but I believe it's going to hurt Vegas a lot.
