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!Awesome!! This tool will be so handy! Thank you so much!
