Where is June suitable for couples to travel? Domestic. About how much?

I don't know where you are. Couples can choose many places to recommend.

In the northeast, such as Dalian, you can choose Suzhou and Hangzhou in the east, or go to Xitang, Liu Zhou and Wuzhen to experience the amorous feelings, or go to Gulangyu to experience the romance of island villas, and in the southwest, you can go to Chongqing and Chengdu.

I think Gulangyu can be considered.

If it is convenient, book hotels and air tickets online in advance. If two people save money, the cost is not too much.

How much depends on your location, destination, travel time and so on.
