Ok!! you are right there are seven competition days but the latest realistic day for arrival would be Tuesday 4th August with earliest departure on the 13th. Whether the Saturday is a holiday or not we still need to be there for that day. So, as far as I am concerned it is still a two week event by the time you travel there and back, not a seven day event!

Hi John,
Problem is, no matter where the event is held, you still have to travel and the organisers can't be held responsible for that one. When I was the the JWM in Thailand in 2001, I had to wait in London for an extra full week for my box to arrive back to the UK, so that year the JWM was 3 weeks long . . . well for one competitor anyway

When I go to the USA for a 2-3 day event, with travel and set-up the event takes 1 week, but it is still only a 2-3 day event and not a week long event.
Certainly, when the next JWM is held in another country, here would probably be no religious days, but they might have a lot of rain, or something else to make the need for a free day. What the IJMC has said, is that the organisers, for this and all future JWM's have to shorten the event down and this has been done with the addition of more judges to get the flights done earlier.
If the event is too long then it might be wise to consider a different competition with less pilots taking part and a different format. There are plenty out there. But this one is where all jets get to fly in the one comp together. Something worth considering and if we are all going to this JWM, then we all will have our models flown and practiced with so there should be no need for any of the practice days, I would hope.
