10. Travel off-season
This can save you big in a lot of ways. Hotel and airfare are likely to be lower, and Disney sometimes offers promotions like free meal plans or free extra days during periods of lower visitation. If you’re buying a single day ticket (far from the best deal, but sometimes a day is all you have!) they are cheaper during off-peak seasons. Check the pricing calendar on the WDW website to see what days will save you the most. And as bonus, crowds will be lower and you won't have to wait as long for your favorite rides!
