Green and indoors
還剣 shore, Literature courtyards, Thong Nhat Park and Ethnology outdoor houses beat night lanes. Budget rest and air-con; go indoors at midday heat. Ethnology is west — a half-day alone, not jammed onto the end of an 旧市街 day.
What to skip
Skip late ビール通り, 列車通り tracks, and long 陵 queues (plaza exterior only if children cannot wait). Dress still covers shoulders/knees for the 陵. Night: a 還剣 stroll or an early hotel return.
