I think it has something to do with the leap year. You get an extra day in the year so, you get an extra day to your vacation! That would be a huge savings for us also!
Well I hope it is more than an extra day on your park ticket since an extra day added to a longer ticket is only like $8 per ticket. We are going in January and will be upgrading some two day passes to 7 day passes hopefully it is something we can take advantage of
nicpries...I just posted this over on easyWDW. I hope that was okay.
