Datong to Dalian travel consultation.

The prices of hotels in Dalian are divided into off-season and peak seasons. The 358 yuan hotel you are looking at now should be a 3-star hotel. It will definitely increase on May Day, and it will probably be about a hundred yuan more expensive. Hotels can be booked online on Ctrip, Elong, etc., which will be cheaper.

Compared to other cities, food in Dalian is more expensive. It depends on the person and what you eat.

You can ask your girlfriend about places to visit. Since she is in Dalian, she may have been to some scenic spots. I'd better ask for her opinion on whether it's worth going again.
