Sheraton-purchase park tickets

[KatieKepic]

I'm finding conflicting infomration online regarding purchasing park tickets if staying at the Sheraton. I tried contacting the hotel but with the language barrior, I'm not sure they understood what I was asking. I'm trying to figure out if we can purcahse tickets at the hotel or if you can only do that with the Disney package? We're not 100% sure how many days we want to go to the parks yet so I was hoping to be able to just purchase once there day by day.
