Depends on your travel party. Uber/Lyft is the cheapest if all adults, but for 10 people, you will need 4 cars so a party that large may actually be cheaper to get a car service.
We always use Tony Hinds, as previously mentioned a lot in this thread, never had an issue, and most importantly felt safe traveling and secure knowing he will be there at the exact time we requested. We almost always do Disney and Universal on our trips. We usually use DME from airport to Disney then Tony (or Noelle who works with Tony) will take us from Disney to Universal then from Universal to airport. We are a family of 5 with 3 kids, always have needed a car seat, just let him know how many you need and they will be on the van for you when being picked up. I do not think 10 people will fit in one of his vans, but he has multiple drivers so 2 cars may be needed.
