I am still using it obsessively - just came upon my dining res. on June 13th that I had been watching for almost 6 mo! Up at the crack of dawn (3 am for me) four days in a row (1st time for first 10 days, then one each for the rest of my vac. days) and got all the dining I wanted!! All because I knew exactly when to do it (because I checked at least 150 times prior to make sure). This calculator is the best! And I'm gonna do it again for my fast passes! See, I have that to check on repeatedly until October, in case I forget, or think it was an illusion. This really helps to constantly feel like you have something to look forward to. Thanks WDWMagic!
