Help W/The Order Of Events At The Reception~

Hey, my Quinceanera`s gonna be in August 21, 2004 and my mother and I are having a difficult time trying to figure out how the order of events should be at the reception. I would really appreciate any help given. In what order should the vals, presentation, ultima muneca dance, coronacion, regalo sorpresa, baile sorpresa, brindis, ect take place?

If anyone of you has had a Quinceanera before, what order did you guys do all this?

Thanks a lot!
