Add a new rule entitled “Tanning”:

As a weekly action, but no more frequently than once every 24 hours, any Tourist may choose to Tan. To do this, they roll DICE5 in the GNDT with a comment of “Tanning” and add it to their Tan statistic.

Add a subrule entitled “Sunscreen” to “Tanning”:

If a Tourist wishes, he may choose to wear sunscreen by making a comment of “Tanning with sunscreen”, instead of the usual “tanning” comment. If a Tourist wears sunscreen, they reduce the number that they increase their Tan by, to a minimum of 1.

Add a subrule to “Tanning”, entitled “Staying indoors”:

If a Tourist has not tanned within the last 7 days, any Tourist may decrease their Tan by 2.
