17th - Tay Ninh is a fabulous real Vietnamese city, relatively untouched by the west and tourism. A great choice by us to off-set the bustle of Ho Chi Minh City and the tourism of Vung Tau.
On the way back to Ho Chi Minh we visited the Cao Dai Great Temple (Thanh That Cao Dai), the Cao Dai Holy See, founded in 1926, is 4km east of Tay Ninh, in the village of Long Hoa. As well as the Great Temple, the complex houses administrative offices, residences for officials and adepts, and a hospital of traditional Vietnamese herbal medicine that attracts people from all over the south for its treatments.
This is a most  impressive facility centred on the temple and has a vast array of followers, teachers, monks and is visited by millions per year. They even have a their own resident families of monkeys. The visit had a strong emotional impact on Roberta.
The car ride to Ho Chi Minh City was uneventful but again provided a display of the variety of landscapes, industry, transport and diversity of this land. 
We arrived mid afternoon and after checking in headed of to reconnoitrer the market. We were on a mission to purchase a new suitcase for Roberta whose existing case had a malfunctioning retractable handle. We first stepped into a shirt stand and for the next 30-40 minutes we jousted with the lady sales folk which was great fun. The sales folk had amazing skills of selling, negotiation, flattering, outright sexual innuendo, and make exit almost impossible. Both Roberta and I purchased shirts and managed to escape with our wallets and dignity almost intact. Shirts are great, dirt cheap and overall good buys. We headed back to the hotel to re-group. We planned to attend that evenings night market which we learned started at 7:00pm.
We had some early dinner, Pho, and then down to the market. There was considerable activity in the side streets but no market - it was 6:30. We took up position at a local café and waited.
At 6:45 the most amazing, orchestrated event took please when hundreds of people with hundreds of pop-up gazebos flooded in like a tsunami, followed by bikes towing large metal boxes full of goods. 
In the next 10 minutes the market sprung up from the ground to fully equipped and lit stands offering everything from food, trinkets, clothes, shoes, hats, and of course bags and suitcases. Roberta wanted a full sized case plus a carry-on case. She found what she wanted and then the dace again began. "How much"? - "3million 2 hundred thousand" "Too much" "2million, 5 hundred thousand" "Too much" "2 million" "No" "How much then"? We offered 1 million 5 hundred thousand. After the usual theatrics we did the deal - 1 million 5 hundred thousand dong - A$90.00.
We dragged the case and ourselves back to the hotel. Tomorrow we have a city tour for our last day.
