Something doesn't sound right. There must have been a reason your friend was asked to leave the hotel.

Any change of residence while on probation should ideally be approved in advance by either the probation officer or the court. Sometimes, special restrictions apply, such as not living with minor children or within a certain distance of a school. If the probation officer is unreasonably withholding permission, your friend should file a motion with the court seeking the court's approval of the proposed residence.
It is unlikely that your friend is correctly understanding or reporting to you the instructions of his p.o. In any event, p.o.'s are not laws unto themselves. Your friend can contact the manager of the local Probation Office and ask for intercession with his assigned p.o. It is highly likely that some clarification and resolution will be forthcoming.
My responses to questions on Avvo are never intended as legal advice and must not be relied upon as legal advice. I give legal advice only in the course of an attorney-client relationship. Exchange of information through Avvo's Questions forum does not establish an attorney-client relationship with me. That relationship is established only by individual consultation and execution of a written agreement for legal services.
