hello there!
well first of all I have to tell you the calendar wont be revealed until april-may at earliest (as far as I can recall, maccie?)...
second: there is a chance the clubs open late but I also heard rumours about space and el divino opening early according to mcrackin somewhere on these pages...
yet: you will sometimes be able o figure out what it will be like by checking out the last calendar.
naturally some nights are changed but the likes of cream and manumission are steady nights and will return to the island, 99,9 % for 2005 on their regular schedules. others like la troya, school disco, clockwork ect and whatever else nights there has been thruout the last 5 years, are more likely to change and not reappear.
hope this is ok enough info for you!
