Don't forgot guys that they budget so well that they often have 'free' holidays like the planned DLP trip that was cancelled just before Xmas last year.....you know the ones where they use the annual train ticket that definitely didn't cost more than a single journey. And use the annual park passes that absolutely don't cost more than a 3 day ticket.
That holiday was so free that Sian didn't buy them all thermals because of the weather only for the trip to be cancelled.
I think their next WDW trip is in October...so easily enough time for another 7 holidays before then.....
