I am no expert but those who are feel that reusing memory locations without any difficulties is itself an expert skill. Some experts recommend building a journey for the specific purpose of reusing it after each short term use. In another words for expert things like demonstrating expertise at remembering number sequences or card decks. Once used and displayed, it has no further use and can be repurposed. But it seems to me that reusing a journey that you have already deliberately loaded into your long term memory is just asking for ghosting issues.
I take it from your description of why you are considering reusing memory locations is that you are currently locating one memory object at each station. What if you located an image of an Ikea piece of furniture with five drawers at each station/ Now instead of maybe ten locations, you have fifty. Then use the chain method to locate one memory object on the outside of the drawer and one memory object inside each drawer. Total is now two hundred and fifty. Next add another set of drawers in a different color at each station and repeat. Hundreds of locations in one short journey.
Do the same for the hallway from your apartment door to the elevator, the inside of the elevator, the elevator lobby, the hallway from the elevator lobby to the parkade, the walk through the parkade, the dashboard of your car, the exit gate from the parkade.
If not your apartment, then where you work, or where you go to school, or your friend’s apartment. At least a thousand, more like thousands of locations. No need to start reusing established locations. The problem is to avoid being overwhelmed by the sheer number of inviting locations just waiting for you to use them.
