rumor has it, that they no longer are doing the virtual queue and it's now stand by. You have to be in "line" 2hrs before the parade starts to get a spot and spots are extremely limited. I have seen enough video and pictures to show they are not filling up the floats like years past since they are pushing people to pay for the experience thru the ride/dine package.
Honestly if it's truly something that you want to do just buy the dining package and save yourself some aggravation.
