The problem with hungry shark night is that its over so quickly. One evening - hell, one hour - and all the good games ™ are full. If you miss it, your chances of getting into a game you’d like are fairly remote. And then, its over, and you’ve got nothing to do but make costumes for three months.
The US’s Intercon has a solution to this: they split their signup across multiple weeks. On the first hungry shark night, you get to pick one game. One the second, you get another. And so on, until everything is full. Details here:

Oh, and they make you pay to get to select games. Up-front money. Ouch.
I wonder how well it works in practice.
