Jozi indoor afternoons: how do you plan a good backup day?

A backup plan is more useful when it already fits the group. Instead of turning a cancelled outing into a scramble, this thread invites ideas for indoor afternoons in Johannesburg that can be adapted to different interests and energy levels. Start with the purpose of the day. Is the group hoping to talk, learn something, keep children occupied, make something or simply spend quiet time together? Choose one main activity and check its current opening, booking and access information. Include a realistic travel plan and an easy place to pause. A home-based version can work too: a shared cooking project, a board-game afternoon or a small repair session. Explain what preparation is needed and how guests can participate without buying special equipment. Disclose a business connection when suggesting a venue. What is your favourite backup-day format? Describe who it suits and how you would simplify it for a smaller budget or shorter afternoon.
