Yes it is normal.
When coming to a stop there is a "load" on the engine (transmission).
When shifting into park the "load" is off, so the engine will idle a little higher until Idle Air Control valve moves to reset idle, a few seconds is normal.
Idle will increase when in defrost mode, AC mode, steering wheel is turned etc.
