We have a Belgian version of the show, and I always wonder how it's possible that they start such fights in such a short period of time! I mean, even if you don't like the new rules, it's maximum a week that you have to live with them!
I always wonder what some of those people think afterwards about their childlike behaviour when they see the show on television.
There is also a show like that, where two families go on vacation together, one week like family A uses to go on vacation and the next week the way family B vacations.
Sometimes, a family likes to vacation in rather extreme conditions, and I wouldn't like to spend a week like that either, but hey, if you apply to be on the show, you just KNOW something like that can happen! But there are also those families complaining when they go on a deluxe-vacation! Ys, not everyone likes deluxe-vacations, but only whining and complaining about it is... immature.
