Legoland - October

Hi, Looking for info about going to legoland for the fireworks in october. Does anyone know what time would be the best to arrive at as we are going from ireland and would like to make the most of it. Where is the best area to view the fireworks from. Is it very very busy. are all the rides open and if anyone out there has been and can offer a extra info that would be great. thanks a mill.

We are really looking forward to it as its a birthday surprise for our children aged 3 and 5, so we really want to make it very special.
