The Pedant revolts again

A local estate is holding an open day in the near future.

I don’t know if the printer of the publicity leaflet ran out of punctuation marks but they have left me confused.  Apparently the attractions on the day are:

“CREAM TEAS, PIMMS & ICE-CREAM GUIDED MEDITATION IN NATURE GAMES & COMPETITION FOR CHILDREN.”

I have no idea what “nature games” are, or how they involve meditation.  Is the meditation during the games to be guided only by ice-cream or by both Pimms and ice-cream?  Further clarification is required.

It might be worth the compulsory “donation” to a local charity as an entry fee simply to discover what one must do in the competition to win a child.
