I have done a lot of traveling over the years and since I have been enjoying the hobby I come to realize that I spent many nights in hotels next to providers.  I can remember many nights in different cities where my neighbors seemed to be fucking like rabbits at all hours.Lol  I could hear someone getting off the lift and going into the neighbor's room and the marathon would start all over again.    

Once you get into this world how you notice things that you may not have noticed in the past. Young pretty lady checking in by herself at not exactly a tourist motel. Leaving a room late afternoon dressed for a party. Certainly age inappropriate.  I was blind for years but now I see the light. Lol.

when a bed's headboard is banging against your wall.  I wish the damn hotels would not put them so close to the wall in the first place.

There are many hotels I don't go to for that very reason.

I stuff the extra pillows in between the mattress and the headboard.
Problem solved.
Last woman though was role play crying so I said "shhh...they're going to call the cops!"

hotels should be brothels

Marriott hotels do not have headboards......one of the reasons I am a Platinum Member.  

I have been traveling, mostly on business, since 1981.  I have spent at least, and this is conservative, four years of my life sleeping in hotel rooms.  Only once did I hear a couple fucking next door.  It was in Florida and they were either coming back or going on a cruise (Luggage was outside the door with tags).

who was alone. Most times they are checking their phone for the room number in a text message, my thought.

Your "thought" is just your imagination running away from you. Hookers use the "two call" system, not johns. Even Johns know the room number before getting on the elevator, otherwise they wouldn't know which floor to go to. Hookers usually know the room number before even heading to the hotel as Johns don't use the "two call system" and usually give both the hotel name AND the room number at the same time, unlike hookers who don't usually reveal the room number until a minute or two before the scheduled appointment.
