Yes we are. Haven't booked yet.
We went last year on the Sunday after ds birthday - end of nov.
It was a cold crisp day, really quiet to all rides were a walk on. Lovely festive atmosphere, lots of Xmas music, trees, xmassy show with snow, reindeer, polar express 4d etc. fireworks at the end of the day.
We went to the grill restaurant for lunch - really nice, Thomas on the tv screens, usual pub fayre / price and quiet - great for warming up.
We are doing the same this year the Sunday after his birthday as it was so much fun!
