Is it okay to get married in a hotel without a bedroom?

You can't. When the bride gets married, the hotel requirements are still very high. First of all, it must be a suite, including a living room, a separate bathroom and a separate bedroom. The living room can be used for the elders, and the bedroom is used for the interaction of the bride, bridesmaid and groom, so there must be a bedroom. Marriage means that the woman marries the man's house.
