I went to this today. Some bits were good, some bits were utter shite (they had an Ewok Village which was so crap it was comical).
It was pretty busy to be fair so that meant A LOT of queuing. They had VIP tickets to supposedly jump the queues but loads of people had them so you just ended up in a queue anyway. The VIP 'meal' was a meat pie with some mushy peas served in a tent.
There are a lot of people kicking off about it on the Facebook page. I was with a little one who really enjoyed it so that's all that matters to me to be honest. I also met the guy who played Biggs Darklighter who was awesome and there was a girl dressed as Oola (the real Oola was there too) who was pretty damn hot!
