Firstly, I would say that if you choose to go by taxi, do not get it to drop you off at the theme parks as they charge taxis just to enter the car parks. The best way to get around cheaply is to take advantage of the Disney buses as they are free, and very frequent. so if you are staying off Disney property then take your taxi to somewhere like Downtown Disney (no charge here) then use the buses.Personally, I found driving a car around inconvenient as the car park is never near the entrance! Disney buses pull up right outside the gate, but again, if you’re not staying on Disney property you may find it too much hassle and may just want to rent a car. most hotels up and down International Drive will run their own bus service into the main parks, but they stop running into Disney after lunch time and the returns out are every hour until park closing.As far as the airport goes, you should find there will be a Mears transport desk that can get you a round trip ticket to and from your hotel.
