First, let me say that my adoptive family (my better half’s sisters, parents, and extended family) take wonderful care of me. As a history buff (and holder of a BA in history, if you must know), they took me to Sukhothai, the capital of the first Kingdom of Siam (back in the 1200s).
When people talk about Sukhothai, they are actually (most likely) referring to three nearby medieval site: Sukhothai, Si Satchanalai, and Kamphaeng Phet. We checked the first two (Si Satchanalai is about 40 minutes drive from the actual site of Sukhothai.
While many of the important sites are in large, park-like areas, where it is traditional to rent a bicycle and pedal around the area (I did), sites are also somewhat randomly scattered about. There was a wat (temple) by the side of the road, some walls in a highway median, and a good sized wat and associated temple grounds directly behind our hotel.
