There’s an early start in Ho Chi Minh City as it’s coffee in the park with the Saigon songbird lovers club. Then they’re on to the Independence Palace, the storming of which led to Saigon’s surrender in 1975. The tour are delighted when Francis surprises them with a meeting with Dubliner Christina Noble at the Sunshine Centre that Christina’s set up as part of her Children’s Foundation. The tour continues with a trip to the fantastical Cao Dai Temple before visiting the famous Cu Chi Tunnels, which were instrumental in Vietnam’s defeat of the Americans. But with torrential rain, tiny passageways and bats galore, will any of Francis’s tourists dare to go underground?
