I travel twice each winter on “girls trips”—- sometimes internationally. Once with my SIL (a longer trip). Once with my BFF x25 years (long weekend). In the last couple of years, I’ve started also doing an end of the school year trip with college aged DD (long weekend). We share rooms, with 2 queen beds. But, these are probably the only 3 people on the planet besides DH I’d share a room with and consider it a vacation. We’re all very compatible travelers (and sometimes the SIL trip and DD trip get combined)— introverts who can read at night in the same room and nobody feels the need to talk or gets offended. We can chat. Or not. People I feel very comfortable with.
Now, an extrovert, chatter, someone I don’t know as well (and this includes travel my mother, you can decide which category or caregotoes she fits in

), I need my own room.
The test is: is this someone I feel comfortable being quiet with?
Hard to imagine traveling with a large group of women. That’s introvert h*ll.
