I think it'll have a significant effect. In times of economic downturn, anything which relies on discretionary spending will take a hit and holidays are one of the first things many will cut from their expenditure. Even amongst those for whom they remain a priority, their annual second, third and fourth WDW trips are likely to get the chop. Brits make up little more than 1% of total visitor numbers, so what we choose to do won't make an enormous difference either way. Not so the impact of American travellers. Expect to see more offers aimed at pulling in crowds (such as "free" dining) over the coming 12 months.
