If they all jump to the earliest possible dates
9 and 10 that will be a problem. Maybe ONE of the big ones will try it later
it's not impossible, but unlikely. which one then?
pacha have already announced music on and solomun close on 8,9 and 11 oct. I can't see them going for another week without any big artists and also pacha restaurant reservation system only works until 11 oct which makes me think that unless something changes, 11th october will be their summer closing with the usual extended solomun+1 closing session.
hï and ushuaïa have already announced their joint closing party, odyssey, for 10th october.
so the only other big (relevant) one left is
amnesia. they've so far announced elrow closing for 26th sep, together for 5th oct and paradise for 7th oct. seeing this, it's very unlikely that they do nothing on the weekend the above ones close and move their closing to 17th october. one because of staff, two because of the already announced parties above, the people will book their closing party trip around those dates. amnesia would be pretty alone if they did it the weekend afterwards.
it's true that their closing will clash with ushuaïa/hï if they do it on the 10th (which is what I expect), but the same happens for the openings in may now. but if they announce it early enough and with good artists (as happens for the opening), I don't think there will be an issue.
as for privilege, unless they pull a super closing party with someone like carl cox or similar, their closing probably sadly just won't be relevant. the last great closing party they had was because that summer afterlife still had a residency in there and because of them they had access to great artists. as always, prove me wrong...
