I agree, I see them as that double-standard type possibly, too. And while they may be well-traveled, it may be that their luxury standard for traveling is much higher than what they will have to endure with TAR. If they are high maintenance, might not last long.
Also, I seem to have misread and confused the sisters, lol-- Marianna is the "mean" one; so, I may end up liking Julia more. Julia might still be the drama queen, though.
