I just wanted to let those planning to buy tickets from authorized resellers such as UT, Park Savers etc. that not all resellers have the same ticket expiration dates and conditions for tickets purchased before October 16th/or when supplies run out. Parksavers tickets, both etickets and plastic cards expire similarly. I just confirmed with Parksavers that "Your first date of use on the ticket needs to be on or before December 31st, 2019. Remaining days on the ticket can be used up until January 14th, 2020." This actually gives us two additional weeks for possible ticket use!
