This would certainly be plausable, but it might be more be more convincing to say (if asked) that, "I will be returning very soon and there is no reason for me cart the suitcase back and forth."
That's because it's easier for most people to tell the truth with conviction than it is to tell a lie...which is something I learned the hard way when I was eight years old (almost 65 years ago).
Upon departue, you could then add that you just visited the woman you love and that you will be getting maried when you return.
