We are planning a trip to Disney in early September - our 8 kids, hubby and I, and my parents. Ages will range from 5mos, 20mos, 3.5, 6, 8, 9, 10, and 11. Trying to fig out strollers. We have a Phil and Teds inline double and a chicco umbrella. I'm wondering if that's adequate or if we should look into a second double. I just saw the post on apple scooter rentals with a CityMini double. I've never done Disney with kids and it's been YEARS since I've been there.
