Ok so this will be our first time to Disney for our family. We have a 12 and 3 yr old. I am trying to do this on a budget. I can't decide if i want to stay onsite, DoubleTree in Disney or at something like the Fairfield Inn & Suites Orlando Lake Buena Vista. i like the Fairfield price at the free breakfast and it also has a free shuttle. Should i scrap it all and go onsite?
