A comment by Cali in another thread regarding unforeseen circumstances got me thinking.
What do you think the Producers would have done if.......
The Guido's had successfully managed to make The Frat, Mom & Emily and Rob & Brennan miss their plane?
If the leg where Guido's and Frank and Margarita "cheated" by getting a taxi instead of a train had been an elimination leg?
Amie and Paul had been come in last during the week where Kim and Leslie forced them out of the taxi they had claimed?
