For the purposes of defining non-transient guest, the guest must enter into a written contract or lease at the beginning of the stay, for a period of at least three consecutive complete months or for a minimum of ninety consecutive days. Guests who do not enter into a written contract or other written agreement at the beginning of the stay but whose stay ends up exceeding ninety consecutive days are still considered transient guests because there is no agreement concerning the length of stay.
