Great job staying sober, pattj.
I agree with Ready, jtlgg, Anna .. . . I would address the issue now while it is fresh in your mind. How deep you want to go is up to you . . . I, personally, wouldn't go too deep or be accusatory, etc. "We will be exploring other vacation/travel opportunities". Maybe, have a few responses in your back pocket if they push for an explanation. "We are looking for experiences which don't focus on drinking", etc.
Glad you navigated your holiday in a sober way; sorry the holidays were so unpleasant. If you broach the subject with your family now, you can start planning your sober holiday now - fun!!!!
