The afternoon parade is on every day - weather permitting. The evening parade, Fantillusion, should (hopefully) be every night from about the 10th Nov.
The bonfire spectacular is very good, but it's over in half an hour - assuming the weather allowed it to go ahead in the first place! But it is one of the few times you will see fireworks at DLP. Still, I agree with upjest doza - I would either go earlier for better weather or Halloween. Or I would go from the 10th November for the Christmas stuff.
