I will visit Xiamen with my family at first week of August.

Well, what's the budget of your accommodation?
Litz Oceanview Hotel is highly recommended. You can see the sea view from the hotel window. And this hotel provides comfortable environment and warm service. The price is about CNY 400 per night. You can go and see. It's located at 298 TAtou She ,Huandao Road,Siming District. Hope you like.

As I know, Gulangyu Island, South Putuo Temple and Hulishan Battery Scenic Spot are must sees. You can fully appreciate the beautiful scenery of the sea. Have a good journey!
