Planning 4 day trip to WDW & USF/IoA (Jan 2016) with family of 5 (staying on-site @ WDW) and was wondering if anyone has used Uber to get between WDW & USF/IoA? If so, how does it compare to Mears or Taxi or renting a car for the day? Can we make a "reservation" with Uber,in advance? Where is the best place to be picked up, dropped off? Is Uber allowed onto the WDW properties? Sorry for all the questions, I'm a newbie (to USF & Uber) and kind of concerned about this part of our trip.
