I had read shortly after the tsunami that it (the shortfall in expected visitors from Japan) was likely to happen.
Postponed booking my hotel in Maui, and then a week or so ago went on to Priceline and got a very nice hotel at a very good price. Did autoslash.com on the car rental and have saved some dollars on the initial rental car booking as well.
Looks like the predictions back in March are coming true.
