I'm one of those folks who did send an email to Celebrity's Executive Office. My concern was not merely changes to menus and the vaping test (I'm against allowing vaping) , but rather no one was notified in advance of either test. For those of us that are affected by vaping vapors or cigarette smoke, those vapors travel and "isolating" those who do to a section of the casino is somewhat useless.
So, in my email, I asked if Celebrity would refund those who have already booked if Celebrity allows vaping on their cruise. After all, that was not the policy when I booked my cruise. The answer: no. Celebrity hasn't come up with a policy and isn't offering refunds.
Since my next cruise with them isn't until next February, I have plenty of time to cancel and will fight them for the return of my non-refundable deposit if it comes to that.
