Bday celebration advise

[Poohtigeey]

We will be at Disney for my DD's 2nd bday. This is more of a coincidence because we wanted a Dec trip before Christmas. Anyway my son turns 6 early Nov. He really wants to have a celebration at a restaurant like his sister. I'm not sure what to do. I know it's not that big of a deal to celebrate a little late, but if a CM asks when his bday is I absolutely don't want him to lie! What are your thoughts? DD will be wearing her pin one day. I just want this trip to be extra special for him too!
