Is it permissible for a traveler staying in a hotel for seven days to shorten and combine prayers?

It is permissible to shorten and combine prayers on a ship for a traveler. If the traveler arrives and intends to stay four days or more (excluding the days of arrival and departure), the ruling of travel ceases for him, and he is obligated to pray the full prayer from the first day of his arrival. However, if he does not intend to stay four days, or does not know whether he will stay that long or less, then he is permitted to shorten the prayer.
