Not really, when you think about it. I wouldn't think the venue for the meal is that big, and certainly won't be large enough to have that much affect on ticket availabilty for the ordinary fan. It's not as if there will be a thousand bankers there jumping on the coaches taking them to the game.
Tickets for away games are much harder to obtain these days. You just have to read the posts from people who have been to nearly every away game over the last few seasons and now can't get tickets to realise something is seriously amiss.
This will probably be the first season in decades I won't go to an away fixture, and I'm more than a bit miffed about it.
