Is it important to plan ahead in order to save on a WDW trip? We want to stay inside DW and I am just beginning to plan. We are free to go anytime of the year and will be bringing our two toddlers(2 and 3 years-old). I can't wait to go, but I would like to save as much as possible on expenses. So with all of that, would it be best to plan short-term or make reservations far in advance?
