Let me say that I"m liking the fact that APAT are constantly seeking to improve and innovate... but there are a few drawbacks to this idea IMHO...
i) It means that at least half the team, if not all, are paying for two nights in a hotel rather than the usual one.
ii) The 3am - 4am finish might be a strain for those who have already spent much of the day travelling.
iii) Half the team could find themselves at a loose end for the second day
iv) If all four of a team"s players were to bust out of flight 1, it kind of ruins it for the four in flight 2.
I could go on, and of course there are counter arguments to all of the above, but as "teamdobb" says above, making this a two-flight tourney will destroy the brilliant atmosphere of these events.
