Hey guys! I’m heading to Houston to catch a game and the Hawaiian shirt lol!

I was gonna ask , I know the rules with a one liter water bottle along with a gallon sized bag.

I wanted to ask if the info on bringing a past souvenir cup or a tumblr is for free soda refills? Is this true so I can pack my souvenir cup for tomorrow?

The cup was from the Playoff game back in October 2023 vs the Twins
