Rashi (13:3) brings down that on his way out of Mitzrayim, Avram stayed overnight at the same lodgings that he stayed at on his way down to Mitzrayim, which teaches us proper Derech Eretz to stay at the same lodgings so people shouldn't think we had a bad experience there the first time.
So every time we travel to the same place, we have to stay at the same hotel?
