TACTIC: Tours within tours
Plan a visit to a traditional heritage site.
Make a preliminary excursion alone and take the official guided tour.
Then go a second time, but now inviting along one or two friends. Take the official guided tour once more, but in the time between your two visits plan a tour-within-a-tour for your friends.
During the official tour, provide your friends with a parallel ‘commentary’ that is olfactory (dabbing their wrists with perfume), sensorial (slipping them tit bits to suck) and, maybe very occasionally, whispered – exposing your friends to critical or complementary tastes, whiffs and comments to accompany the official narrative.
Make sure that you do not disrupt the tour, be undetectable and invisible – a real ‘ghost’ tour - containing your tour within the ‘real’ one.
