This thread has inspired me to be scientific.
My G/F is taking her first trip to Negril.
She is super organized, super efficient, super hard working, and can be (from time to time) uptight.
I'm going to record an interview with her daily (from trip down to trip home) to see if you can visibly chart the "Negril Effect".
This could be a fun experiment if I don't get too laid back to carry it off.

Maybe I should get some baseline footage as sort of a control.
