In Pittsburgh it can be faster to take the bus to the airport than to drive, because there are special bus-only lanes that sneer at rush hour traffic. Not so in Orlando, where the trip takes 45 minutes by car and more than twice that by bus. Today was actually my first venture onto Orlando's public transportation system (such as it is), if you don't count the downtown freebie Lymmo service (which actually counts for quite a lot; it's pretty handy). Anyway, I ventured from home to the airport and thence to a Thai restaurant where we met some friends for dinner, just for the experience.
The driver was friendly and helpful, the cost only $1.50 ($3.50 buys a pass good for unlimited trips in one day), and the bus itself was fine. But the total time—walking from our house to the bus stop (35 minutes), waiting for the bus (20 minutes), and stopping at nearly every one of the multitude of stops on the way to the airport (100 minutes)—made for a long afternoon. Still, I proved it's possible to get to the airport without benefit of car, at least if one doesn't have too much in the way of baggage.
And the Thai food was good, too.
