sunrise in october is around 7am i'd say.
with space closing (and opening), it is always a bit a of a fight to get it all covered. you don't want to miss out on the flight area bit so you wanna make sure you're there by sunset (8pm). then you enjoy until midnight (or 2am if they keep going again like at the opening this year). and then comes the "bad" bit - the 3-4hours when it gets super busy everywhere else because the car park shuts and everyone has to go inside. then from about 4-5am people start leaving again and it gets nicer again. so you just have to set your mind right - enjoy the flight area, have a long break on premier etage (or in el salon) when it's too busy everywhere else and restart again in the wee morning hours...until they turn off the music
