Hi Linda,
The weather in September will be similar to here in England (without so much rain). It will be warm but not hot, so I suggest you bring light, comfortable clothing with some cardigans and jumpers. All the destinations on your holiday will experience the same kind of weather....Warm days and cool eveings.
Throughout your holiday the dress code will be casual, unless you want to visit a top class restaurant where the dress code will be smart, dresses etc....this is up to you.
All hotels provide hairdryers in your room. I hope this helps. If you need any other information, please let me know.
Warm wishes,
Cheryl, your editor
