At the Manchester, NH location for the month of October, if the kids wear their costumes, do they get 50 free tickets?

Yes

Yes check out "Chucktober" on their website. FYI tickets are not the same as play points . Play points pay for the games and tickets are what you get for playing and exchange them for candy or toys etc at the end...but still a good thing to have extra of there!

According to the website, yes

Yup

I do believe so
