Hoi An became a World Heritage site in 1999 because it has been a locus for international trade for centuries. Turns out that was probably a mistake, because the town has now become hopelessly populated with tourist traps and assertive (more often aggressive) beggers and hawkers of postcards, cyclo rides, and tchotchkes.
Finding no restaurants with air conditioning, we ate in a riverside bistro on the terrace. Food was good, but I later regretted having to walk through the kitchen to reach the toilet. Sometimes it's much better not to know where your food comes from.
Nevertheless, we DID enjoy seeing the ancient Japanese bridge and Chinese houses with storefronts, as well as the Chinese Temples.
Our Palm Garden Hotel is a small resort about two years old, on the beach and quite pleasant. Our room was on the second floor among low-rise bungalows with a balcony and view of the ocean. Lush bougainvilla grows everywhere.
