My traveling partner and I will be in Hanoi at the beginning of September for five days and have time for a two-day/one-night excursion. Everybody says you can't miss Halong, but it seems the more I read the more Ninh Binh might be a better choice. September being the height of typhoon season is one reason; another is how spoiled by tourism it seems Halong has become. Advice? Is the scenery in Halong Bay on a one night cruise really that much more spectacular than Ninh Binh?
