We too were there in May, to be met by Storm Troopers at the gate was fantastic, DS (4) was amazed.
There were special guests in the park, I apologise as I cant remember who (one actor and one of the CG effects guys)
And being a lifelong Star Wars fan (although my favorites are still the "first" trilogy - but thats just my age and Harrison Ford) the Star Wards Parade that took place at 11.15 am was just unbelievable. Seeing Darth Vader, AR2D2 and C3PO walking towards you is a sight I will never forget!!
And I sooo wanted to buy the Light Sabre in the store (but at $180 and having to get it home to the UK I had to pass!!!)
