If you are flying into Orlando International Airport, you will have no problem catching a cab or renting a car - there will be dozens of cabs waiting for you and you'll notice that all rental car companies have kiosks there. Renting a car in Kissimmee, especially if you are planning to visit Walt Disney World, is a must. Exploring the area outside Kissimmee is very difficult without a vehicle and you'll find that a rental car is well worth it. Just keep in mind that rush-hour traffic can be a little messy in the vicinities of Orlando.
If you plan on taking a taxi, you can ask the driver for an estimate to your destination from the main taxi stand. Taxi rides are metered, but an estimation will give you a good idea of price and timing and help you decide between a taxi and a shuttle.
