I recently bought a house that has multiple AC units. There's a large 2-stage unit that cools half the house, and a smaller single stage that cools the master bedroom/bath. Ive noticed the 2 stage seems to pull a lot more humidity out of the air, and even if both are at the same temp, there's a discernable change in the way the master feels when you walk between the "zones" each unit controls...

Does anyone have any experience with a dehumidifier in a situation like this? Or any other ideas on how to get the humidity down to a relatable point between the two?

Why did you even post this? Bragging about buying a house...cause you have your answer in your OP, but have a downvote.

Depending on how much area you are cooling in the master bed/bath it could be oversized. If it quick cycles then it won't pull the correct amount of humidity out of the air before shutting down.
Heard an a/c guy saying recently that he installs de-humidifiers a lot, seems there is a need for whatever reason.
Good luck, call an a/c guy.

Dehumidifiers are pretty much made for situations like this.

If you get one make sure to get one that drains into the pipe work under a sink. Carrying buckets of water gets annoying.

I have 3 zones. The bottom floor has 2 that are very similar to the situation you described. The bigger zone was really close to the second thermostat and depending on how I was running the program could frick up the temperature for the smaller zone.

Now I do have a dehumidifier in my air conditioned drinking room. It's only 300 square feet with a garage door so it was staying humid. Works great. They make noise though and you either have to drain them every day or be able to run a hose to a drain.

Bottom line is tons of opions. Probably best to call a professional.

My window unit doesn't have this problem, so I can't help you

The unit will only pull out humidity when the compressor is running. So if a unit quickly reaches set point and the compressor shuts off, you will no longer remove moisture fro the air. This is why over sizing a unit is bad
