Our last day in Hanoi was spent visiting the local markets around the Old Quarter and drinking Vietnamese coffee while stuffing our faces with as much Pho as our bodies could handle. Pho is very cheap, a bowl going for $2 - $4 a pop and is one of the most delicious meals I have ever had.
Hoi Ann
We booked cheap internal flights through JetStar Airlines from Hanoi Noi Bai Airport to Danang Airport, and they also offer a bus service (click here) that runs from the Old Quarter to the airport. It was very cheap to use this bus, and it saved us a lot of stress too once we found the bus terminal (thank goodness for the GPS function on our iPhones). From Danang Aiport it was a good 40 minute drive to Hoi Ann (this is what caught us out the most with our budget, all the taxi rides to and from the airports).
Hoi Ann was our favourite place in Vietnam, and perhaps, in the whole of South East Asia. It reminded us a lot of Siem Riep in Cambodia (lantern lit streets to stroll down at night, great food, fabulous cocktails....it's a wonderful, 'vibey' town filled with something for everyone). The beach was only 20 minute cycle away (most hotels have free bicycle rental) and we were able to swim even in the middle of their winter time. Hoi Ann is most famous for its tailors, so make sure to budget accordingly! We hadn't planned to have anything made, but once we saw the quality of the suits we ended up having two made for Farmboy. Be prepared to bargain. You can everything from swim suits to lace skirts, to silk shirts and suits, as well as every leather item imaginable. In particular the leather boots and luggage looked beautiful. It wasn't incedidly cheap, but the quality is amazing, and compared to back Korea or South Africa, the prices were reasonable.
We spent 2 nights at Thanh Van 2 Hotel which was great, and then spent our last night at the incredible Hoi An Ancient House Village Resort. We like to spend our last night or two in luxury, especially if we have been staying in backpackers or really cheap hotels for the rest of the time. We felt like we were on honeymoon again, and the suite was a very reasonable $90 for the both of us including breakfast.
We also did an early morning tour to Masan Temple to see the ruins. There are quite a few tours you can do that leave from Hoi Ann, and your hotel will be able to help you with booking.
