What would be nice is if they did a "pro" version where everything was open all the time. So if you get at a location at 3 am, you get to go and do the task and not have to wait until the morning when it opens and all the other teams catch up.
Logistically, it would be insane and obviously Phil could only meet the race leaders, but at that point the race would be pretty exciting during every episode.
You know, as for the family edition... I must say the only reason why I like it is because they came to Toronto (and the university at that!).
