While I always hate to see a price increase, I can't help but think there will be an increase in visitors to the Orlando area in the next several months. I've seen lot of reports from people stating they were going to put off their next trip until the mine train opens up. So once that opens - people are going to want to come and experience the new ride. In addition, the Harry Potter expansion will attract huge crowds this summer. For Disney fans who are traveling to Universal - how many of them will be thinking I can't be this close to Disney without stopping in, especially to see the mine train.
While some would argue the Harry Potter expansion will draw people away from Disney, I would agree it would reduce the people dedicating their entire stay to Disney, but I think the increase in single day attendance may be on the rise for those people who want to come and just ride the mine train.
