Is the prayer shortened or complete for a distance of 300 km with a stay of two weeks, and similarly for a distance of 120 km with the intention of visiting only?

The distance mentioned in the first question permits taking advantage of travel concessions, such as shortening the four-rak'ah prayers and combining them, as long as the travel is not for a sinful purpose. As for a stay of two weeks, it negates the right to travel concessions because it exceeds the duration of stay that does not cut off the ruling of travel, which is three days. It is permissible to shorten prayers if the duration of stay is less than four days, and there is no wife with whom one has consummated marriage residing in that place, and that place is not one's original homeland.
