Madeira ideas for a short visit

[GraceApek]

I have three full days in Madeira and will be staying in Funchal without renting a car. I would love to visit another part of the island, but I am trying to avoid an itinerary that only works if every connection is perfectly timed. I might spend one day in a coastal village, and another for a manageable walk if the forecast cooperates. The published bus times seem possible, although I cannot tell how much time to allow for transfers, stops, and a relaxed lunch. I started planning with 3 days in madeira without a car and it helped me list possible places rather than commit to a rigid schedule. Would you reserve the final day for Funchal, in case mountain cloud or a missed connection changes the earlier plans? I am also considering a guided transfer for one walk, while another option is to keep every outing reachable by public transport. If you have visited without a car, which day trip felt practical, and what would you skip on a three-day visit? I do not mind a slower pace between day trips.
