I have a few suggestions for Tomorrowland's Starcade. This comes somewhat as a result of the Laser Tag thread, but also ideas I have had for a long time.
First of all, I think it might be fun to have some Laser Tag up in the abandoned second level on the Starcade. The speedramps could be frozen and act as a queue to the Laser Tag, and I am pretty sure they can organize it enough so it is not full out chaos like at some places.
I also think, in general, they should change the way the Starcade operates. We pay enough to enter Disneyland, so maybe they can make the Starcade free to an extent. I suggest they use the playing cards, as in, you swipe the card in a little slot to play games. Entering the Starcade, they could give you a card with a certain amount of swipes/credits allotted, and then when you ran out, you could either buy more or leave. Most people would buy more, so they still make money, but offer a free sampling of some of the games too.
Third, bring the Starcade's interior more up to date with new murals and a more silver scheme instead of all white inside.
