If I'm that determined to get into a specific game at a con then I wouldn't have scheduled anything else in that slot anyway.
And given that at something like GenCon the dealers' hall and auction stores are can't-miss fallbacks (during the day anyway), I've always got something fun to do.
The key phrase is "during the day". Lots of games at the cons I was at were scheduled in the evening. And honestly, you can only spend so much time prowling the dealer's room.
