The first time I went out to travel with the girl I was chasing, I only knew her for five days, and she also promised to go out to road trip with me. Are there two rooms that night?

Depends on how you want to get along with her. If you are just in love and everyone has their own needs, then you can get a room. And she promised you when she knew she needed to stay for one night;

But if you really like her and want to develop with her for a long time, I suggest opening two rooms, which can prove that you respect her very much; It is certainly beneficial and harmless to your future development;
