I'll second what @fastfreight is saying- do you really want speakers in the dining room? speaker cables for guests or pets to trip over? Sonos are awesome, just use your phone to control, either using Roon from the main system or just your phone apps. We have had some issues connecting them at times when wifi modem changes, but once connected it works flawlessly.
A nice small, discrete room filling sound and no-one will know where the sound is coming from. We have a Five and it amazes me the bass that come out of it. I have also been in restaurants with a few of the little older style One's mounted in the top corners and me being an audiophile could not believe they did not have the sonos sub with them somewhere. I see they even have in wall and ceiling speakers now if someone wanted to do a little more permanent work.
