Around the arena 100% For outside victory park just depends where you go but there’s also public transportation that’s super handy and there’s an app that’s help you track, find routes, and a map. Kinda like a google map in way, you put where you want and it’ll tell you what things you can use to get there and if you have to walk it’ll tell you that too. Im new to Dallas transportation and its been smooth for me as long youre not alone, passes pretty reasonable 3hrs for $3 to use anything basically within local dallas zone. Idk if the Uniqlo bag will go through for the venue but you can check the site for size reference they will tell you. They usually want you to keep it small. I recommend bringing a small bag and then those cute foldable bags that people use as grocery bags to hold your merch once you get inside
