The clubs tend to get busy after midnight, probably about 1-ish. On the whole, they go on usually until about 7am, but many have after-parties which'll see you clubbing for the next few days! (ie Cocoon closing party last year)
I like to go back to the hotel mid evening and take a nap. Wake up, take a shower around 11:30 to midnight. Head out around 12:30 and arrive at the club around 1:00. Sometimes I don't get the nap in though and that makes me cranky! Hee! Hee!
I have a thing where I have to be the first in and last out! So I get there round 12 and stay till the Very end - one exception being Cream@amnesia 2nd august 2001 - but I Had to goto hospital so no lightweight comments pleeease.
If its pacha or El divino i get there early at about 12:30 and sit on the outside terrace drinking for an hour or so then go and have a wander round the other rooms (pacha) and get down to the main room for about 2:30-3:00 or if El Divino stay on the terrace until the main room looks busy.
no set time for going out, if your feeling it can sometimes be hard getting the motivation to go out at night so usually i just wait till i feel better, if that means waiting for space the next morning when your up for it
