Vipes, I should think that this link below, provided by admin, may give you an opportunity to get your concern/proposal on this Sunday's agenda.

It's highly likely that this Sunday's meeting is chiefly about the presentation of the plans for the garden by Museum staff and then an opportunity to ask questions about the plans.

Reading the Horniman Gardens development page on the link below I observe that one of the areas they are considering is ?Re- landscaping some areas to provide quiet areas, activity areas and better picnic spaces.?

This may be the part of their strategy that appeals to you and hopefully will cause you less stress this coming summer.

In your absence, you may find another forum reader who is attending Sunday's meeting, and who feels passionate about banning dogs, to step forward and raise this in the question time?
