Loose the stickers! I will be this weekend, there is always next year! If you are that keen on next year, there is spa next month...! I am very tempted! Its the weekend I finish work and 5 days before tokyo...
Because that sticker is so specific to the event it may be best to take it off, maybe just keep the "24" as a reminder that only people in the know will recognise...
Definitely get rid of the camping pass though, I found it blocks your view a bit...
