Yesterday on my way to see a provider... I was in a very large suburban Boston  hotel. It was crowded with special events.. trade shows and so on..
I texted her, and got the room..
It was all too familiar.. one week ago .. exactly.. I saw another provider in the same hotel.. and as it turns out.. on the same floor (one of many) .. and as it turns out in the room next to the one the girl I saw yesterday was in..  

Sheesh.

Funny thing is when a lady posts a selfie from a hotel room, you can tell by the background what hotel chain she is staying in.

Kinda Scary.  We hobbyest spend a lot of time in hotels, ( so do the providers)

As I sit here and think about my similar circumstances (not many, but, enough to have made a mental note of it); I wonder if the ladies request rooms in specific areas of the hotels to minimize interaction with other guests, be near stairways so the elevators are not always hitting their floor.  Perhaps the hotel staff has a clue and tries to minimize other guest interaction?  Or, is it a numbers thing where eventually lines intersect?

It's  a numbers thing I'm sure. There was no connection between the two providers.

The number of Boston hotel rooms (more than 23,000) came up in a recent thread about hotel rates in Boston.  Of course, not all of those 23,000 are hobby-worthy.  And many are not hobby-friendly (key card elevators, etc.). And there is Provider - Client selection bias (location, amenities, parking) that narrows the number down even more.  There are a few preferred locations that I've found myself in on more than one occasion.  I don't think I've kept track of floor-room overlaps (except for one place in NYC: three different visits to the same general area of the site; THAT was deja vu spooky but I got used to it).  

So I think it was just a statistical Fluke of the Hub of the Universe.  

Many of you know the bar bet about the likelihood of two people having a common birthday in a room of 23 or more people?  There are 366 birthdays (23,000 hotel rooms).  But in a group of 70 random people, there is better than a 99.9% chance that 2 of them share a birthday ... better than 50% that 2 of 23 people will have a shared birthday.  https://en.wikipedia.org/wiki/Birthday_problem

The percentages change for 23,000 (or 10,000) hotel rooms, but the chances of overlaps are still pretty good for small numbers

In May my work travel schedule lined up with my favorite friend. I booked a hotel in Hartford. She had a hotel in Hartford. When the email confirmation came that day, you guessed it, same hotel. I did ask if she'd prefer I cancel and book another hotel, but she wasn't concerned. We've seen each other enough times that I've lost count. There's something convenient about simply taking an elevator to the incall location rather than driving. No worries about traffic or parking.

Saw her again this month in New Hampshire. I'm staying at another hotel and she's coming to see me this time. Interestingly about an hour before her arrival time, I'm walking to my room and the door at the end of the hall facing me opens when I get close. I catch a glimpse of a leg and what looked like lingerie. As I walked by, and continued around the corner to my room, the door quickly closes again. Hmmmm. Yup. I know what my neighbor was up to. And oops! I was not her 5pm.  

Later that night, I'm walking down the SAME hall to find a water vending machine (fun times make you thirsty) and a guy walks towards me, hesitated maybe 4 doors down the hall, head looking left and right at the room numbers, a different door opens and he backs up and walks in. So there were 3 (me included) on that hall in that hotel that night.  

I stay in various hotels all the time. Stuff like that happens a lot, especially on the hour marks. Perhaps we should schedule appointments for, say, 8:45 instead of 9pm?

They'll pounce on your third visit.
