Hoi An is easy to sell, but Central Vietnam weather should be named in the route logic before the group is sold.
The town can be beautiful and operationally fragile at the same time.
Rain and flooding risk should be part of the planning conversation, not a surprise.
A charming location can become difficult if coach access, walking routes, or flood exposure are weak.
Cooking, craft, food, museum, and hotel-based options can protect the day without making it feel like a downgrade.
The backup plan should be specific enough to protect confidence.
Check where the coach can stop and how far the group must walk if weather is poor.
Rain can change timing. Restaurants should be prepared for group changes.
If Hoi An has one must-do experience, do not stack every promise on the same weather-sensitive window.
Share the group profile and the current route. We can flag the operational assumptions that should be clarified before the proposal is sold.
