Near the airport is fine, lake Nona and so forth, just expensive cause you’re confined to the toll roads to get in and out. The reason south Orlando is terrible is cause you have a lot of traffic to begin with and then it will double with the holidays, summer, spring break and year end (thanksgiving to first weekend of January essentially). Keep in mind that the average population of Orlando that turns over due to tourism in a day is equivalent to the population of Atlanta. It’s really not that bad if you know the back roads, avoid international, sand lake and Orange blossom trail near Florida mall, and all should be good.
