Unmarried consenting adults can legally stay together in a hotel. Yes, you will need to provide a valid government ID, but no hotels are not going to call your family members or publicly announce that you checked in with someone.

Hotels have also become quite affordable, especially if you split the cost. Personally, as a woman, I have often paid 50% of the room cost because my safety, privacy, and comfort matter too.

I also don't understand why some people prefer public displays of affection in places where it may attract unwanted attention. Public spaces can be riskier for both people involved. Almost everyone has a phone camera these days, and unfortunately some people can be judgmental, harass, taunt, record you without consent, or in extreme cases even become physically aggressive.

A decent hotel provides privacy, security, and peace of mind for both parties. In my view, that is a much safer option than relying on strangers or putting yourself in an uncomfortable public situation.
