My bedroom temperature varies too much compared to the rest of the house.
It's colder in the winter and hotter in the summer. The thermostat for
that part of the house is on the other side of the living room next to the
guest bedrooms. Playing with the vents hasn't helped.

I can move the thermostat, but that might screw up temperatures in the
other bedrooms. One of them is used as an office. How about hooking up an
additional thermostat in parallel with the one in the hall? Would that get
me the benefit I'm looking for, or would I just wind up with a different
problems?

Hi,
Simple answer, No.

Different problems. If too cold in your bedroom, the heater would kick on
and make the temperature elsewhere too hot. Likewise for cooling.

Trivial: Is there sufficient return air space from the bedroom to the rest
of the house (sometimes a carpet can block the space under the door).

Easy: Consider shutting off the furnace and using a space heater for the
bedroom at night.

Harder: Rework the duct system to furnish more air to the bedroom.

Or get a thermostat with a remote sensor. The OP probably doesn't care if
the otherside of the living room is poorly regulated at night. Move the
sensor into the BR at night and return it to the LR during the day?
