Is there any way to stay in a hotel for free?

Our daydreams about staying in a hotel for free are nothing more than the following three kinds:

1. Travel frequently due to work (you can live in a big place or a special place within the poor standard).

2. Stay in the bar of family and friends (family members often travel or hotel lovers)

Our family is very rich and has our own hotel.

After contacting the credit card, we discovered the new continent, and the idea of staying in a hotel for free broadened a lot. For example, use a credit card for free room nights, and use points to change rooms. Credit card for free room accommodation.

This kind of credit card provides real free accommodation, provided that you can manage it well and reach its threshold, such as paying the annual fee, reaching the consumption standard, invincible ... before you can really get a free hotel.
