Hate it!, Hate it!, Hate it!, LOL. I usually wear a long trench coat, dark glasses, and a hat pulled down over my eyes to kinda blend in---JUST KIDDING

My preference nowadays is pvt home--mine--, or vacation house rental, or motel with outside entrance to room---since I am the only one that she will be visiting, and she is dressed like a travelling lady---toned down, there will be no notice of excess traffic in and out of my room

) I also like busy places, where I leave one of my keys inside my gas cap for her to pick up and just sashay in like she belongs there

When the lil head takes over and I have to do the walk, I make sure I get instructions on where the elevator is located, I dress in earth tones to blend in, carry my brief case, etc., keep my head up and smile, and refuse the housekeeping ladies offer to help me---EEK! I also insist that the lady behind the door stand there and open the door when I put my dummy card in the slot and hand on the door. NO KNOCKING!!!, OR if the door is slightly ajar, is O.K. AND I like being the first appointment on the first day---you know---that does not draw the dreaded "hhmmm, lot of traffic in and out of that room." Just my 2cents, others will be comfy with their own entrance and exit strategies
