It's really up to you whether or not you let the incident completely ruin your vacation. The entertainment director might be faulted for not exercising a little tact, but you're the only one to blame for going off the deep end. You claim only to have wanted to raise a concern, yet your tone suggests otherwise...IMO. No one intended to cause you offense, but you took it anyway and made a big deal about it. Now deal with the response - next time find a hill worth dying on instead of fighting a senseless battle.
