Currently, the reservation system is shutting me out for the end of August as a guest of Grand Californian. I have a 3 day ticket, within the 120 day window to reserve for Aug 29, 30 and 31. , But Aug 26 through 31 is hashed out as "days not available" for my tickets. Have not been able to get a straight answer from Disney chat or via email yet. I may have to cancel my package and do tickets separately, as the parks are "wide open" for non hotel guests on those days (per the chat CR and when I look at the stand-alone system). Makes me rethink staying there at all - as its a lot of money for this kind of hassle.
