Sheri, No.
When we sailed on Diamond open bar, free kids, and CCC, there were a couple of men in tuxedos at Captains Party and again for SSS. No problem at all. As Radisson states dress codes as minimums (including the statement if I remember right of "elegant resort wear"), you are not in violation. Anyone that is uncomfortable, is someone who thinks they might not have made the minimum that they should have.
Now, if you pack "formals" all the way to PiP, I will think something is strange "upstairs." :D
