You will not be quarantined in the following cases, unless the Communicable Disease Control Physician decides otherwise in his/her assessment:
You have received two vaccine doses and it has been at least one week since the second dose. Two doses of the vaccine provide good protection against the coronavirus disease and its severe forms.
So just find somewhere to stay till you test negative on a rapid test (assuming you're fully vaccinated?), you don't need to officially isolate and don't need to advise the hotel though you probably want to get a room to yourself.
