@Aitan_3 stated (a few pages back) that the first three dates were on successive weekends. I found no mention in the game regarding any such time lapse between dates 2&3. Another problem is that Elena had to convince Rachel (no mention of Elena's dad) to let her and D stay on vacation a week longer than planned.
Then, in 0.13 Rachel announces that the girls' 14-day visa is set to expire that very day so they must rush home.
The story's timeline has been seriously messed up. But a few well-chosen revisions puts everything back on a plausible schedule.
The larger question/discussion should be : why was basic storytelling allowed to be so messed up ?
