Hi, I made this journey in last year. Mandvi is a place where they are building ships by hand. Other than that I wasnt particuarly thrilled, however I did visit some craft villages in the area as I was interested in that. If you can go north from Buij and check them out. I have some more info and photos and if you are interested just holler and I will post them.
There are a couple of decent places in Buij, and one is called the KBN hotel on station road. There is another hotel across the street from that , I think it is called the Prince. You can purchase alcohol there (after appling for a permit as Gujarat is dry) and the restaraunt is good.
There are some incredible textiles in the area. A good start is the curator of the museum in Buij, he knows the area quite well and is very pleasant.
Ahmedabad is the start point for train to Buij (overnight trains run to save your daylight hours) , and I then hired a car to see around the different villages. Thre are lots of places off the beaten track in this area and I am glad I took the time to explore them.
Hope this helps, oh and as I said before on the other site~ there is a great place to eat in Ahmedabad and it is called the house of MG, I had one of the most interesting and delicous meals of my life there. Have a great time!
