I would never have thought about using Uber/Lyft for transportation options. For those who have used it, how quick are they and what are general costs?
FCDub's suggestion of rideguru above is a great place to start. You can also get fare estimates from either the Uber or Lyft websites.
Prior to actually ordering a ride, you will see an actual fare quote in the Uber or Lyft app for your specific ride. The vast majority of the time, that is the actual fare you pay. I recommend having both apps on your phones and checking both companies prior to ordering, because both use dynamic pricing and there can be a significant fare difference sometimes.
Also be aware that both companies run promotions, so check those before you actually set your app up to use. Also be aware that many promotions are market-specific. The first (and only) time I used Lyft was in Chicago, and once I left Chicago none of the promotional benefits applied.
How quick?
REAL quick. If I order a taxi from home, my wait is 45-60 minutes. Uber is 2-3 minutes; Lyft would be 7-10 minutes. But that's in the suburbs of Miami. If I'm downtown, or over on South Beach, I can see several Uber logos within 100 yards no matter which direction I look -- they are everywhere!
Rideshare depends on "saturation" of both riders and drivers for its efficiency. In major cities, you are usually within just a couple of minutes from the nearest driver. Orlando is, of course, a major market -- so U/L cars are everywhere, and most drivers drive for both companies. This is not true everywhere, but in Orlando, there is probably little if any difference in pickup times between the two companies.
