Fun Pass Europe?

[newistcruiseaddict]

I'm trying to research the fun pass. I see its basically a higher value than whats paid but this has either changed or completely different in European markets. This is pasted from my current booking on the Divina out of Genoa: Prepare for all the fun you can handle and purchase your Fun Pass now. Valid for all guests in the same cabin, with the Fun Pass you can enjoy unlimited access to all attractions. Feel the rush while speeding through all of the Grand Prix official tracks in the Formula 1 Simulator, experience multiple new adventures in the Cinema 4D, and perfect your strike - bowling as often as you wish at the mini-bowling lanes. 

 

So my question is, if it is unlimited, and valid for all guests in the same cabin, why do I have the option of purchasing it for all cabin members? 

 

Answers greatly appreciated!
