The day before departure, they proactively contacted me via WhatsApp to remind me to arrive on time. On the day of the activity, there were a total of five tourists, including myself. Because it was the rainy season, it rained heavily when we met in the morning. However, since we were traveling by train the whole time, it didn't affect the itinerary, and the rain subsided after we arrived at the laundry. After meeting at Churchgate Station, the tour guide, Alam, took us in order to (1) Mahalaxmi Station to see Dhobi Ghat Laundry, (2) Dharavi Slum at Mahim Station, and finally (3) back to Churchgate Station to see the Dabbawalas lunchbox deliverymen. The train arrangement was quite clever, skillfully avoiding the rush hour. The whole activity was very relaxed, and the explanations were very in-depth. It's a great way to quickly experience a side of Mumbai life in half a day.
