Actual experience: we lived in Coral Gables and I worked in Sunrise, by Ft. Lauderdale.
Coming home one night, I saw a HUGE RV pulled off the highway entrance and a man, woman and child staring up at the roadway signs. I pulled over and asked if I could help.
Turns out they were French--and only spoke French. I...don't speak French. Through lots of choppy sentences, I figured out they had flown into Miami, got the rented RV and were trying to find Disney World.
Without a map.
I got my Florida map out and pointed out that they were at least 4 hours away from the Universe That Is Disney.
They seemed surprised.
First I tried to show them where they were, relative to Miami. Then I tried to plot out a route for them that they could follow, including trying to indicate that some of those roads were toll. The universal symbol of rubbing your finger tips together and pointing to the road actually worked!
Finally I just handed them my map, pointed up to the highway sign that would get them started northwest and said Bonjour.
Since I can get lost going around a block, I sincerely hope they still aren't out there circling around Lake Okeechobee.
