When to buy tickets?

[Peter_noPan]

My family is going to Paris this summer and have our rooms through DVC.

I see we can buy our tickets for the parks (3 days) now on the official web site.

Is there any reason to buy them at check in rather than just getting them now when it appears they are running a deal?

none whatsoever - its usually a fair bit cheaper to source your tickets/annual passes in advance and have them before you go.
