The ESPN Hot Dog was just way too big. Since we stayed at the BWV the time I had it, I decided it would be ok to take it back to my room after a day at the parks. Three days later (thanks to the refrigerator in the room), I was still trying to finish that hot dog, not wanting to let it beat me (it had become some sort of sick personal quest by that time), and swearing that I would never again fall victim to the lure of that giant frankfurter.
Go for the one at Casey's. It will cause you less pain, both mentally and gastrointestinally.
