That's exactly my point - if she is too smashed to answer a simple yes/no question "Do you want to have sex with me?", then she is too smashed to go with someone "willingly" to their hotel room for sex. Here are two hypothetical scenarios:
Scenario 1. Guy A is at a party, where he finds a drunk girl. He asks her "Do you want to have sex with me?", to which she mumbles something he interprets as "yes". He proceeds to have sex with her.
Scenario 2. Guy B is at a party, where he finds a drunk girl. He asks her "Do you want to come to my place and have sex?", to which she mumbles something he interprets as "yes". He calls a cab, takes her to his place and proceeds to have sex with her.
In both cases the only thing that matters is how drunk the girl was. If she is not drunk enough, in control of herself and able to make decisions, than both cases are not rape. If she was drunk enough so she wasn't in control of herself and her decision making was impaired than both cases are rape.
