We are a Aussie family (with a 14 and 15 year old) planning a US trip in mid-December with Orlando being our first stop on the East coast. We plan to spend 4/5 days in Orlando dividing our time between Disney World and Universal studios. Any advice about accommodation would be greatly appreciated. Are we better off staying in one of the park accommodations or in accommodation elsewhere in Orlando e.g.. not far from Downtown Disney? Any tips for discounts etc for first timers?
