This is driving me crazy.. It had to be in the 80s. It was about 2 sisters.. one older and one younger. I think they were aliens on the run trying to get back to their ship to get home. They had similar hair if I remember correctly and a streak of blonde or white in it… The older sister had dark eyes. I think there was also a boy she was in love with.. a human boy.. and I think there was a cabin they went to with an “elder” or something.. I think they ended up staying on earth though.
