Yup, the projector screen is really too small and as the ballroom is long, guests at the far end won't be able to see the screen clearly.
The setup of the ballroom was not bad and I like the centrepiece deco for the VIP tables! Guests' tables deco was alrite and the pedestral stands along the march-in aisle was quite nice.
One thing that I don't really like was the much hype-about ceiling, which was stated to resemble a constellation of stars...I find it quite normal la..
Anyway, about the projector screen rite, I remember Tiffany said that there is one motorised one near the end of the ballroom (away from the stage). You may want to check with her whether if you can use it but definitely, you will need to have your own projector...otherwise, rent from the hotel!
