My T told me that he was going on a cruise over six months before he did. He's gone now and won't get back until October 31/Halloween. I didn't really talk that much about it beforehand, although we did a little bit. (actually we talk/deal with abandonment fears frequently, though). T lets me email him while on vacation, which helps, although his connection is intermittent. Also, I know that I can talk with him about anything when he gets back, including him being gone.

I find it confusing that your T tells you not to talk about how you feel about her vacation/being gone. It sounds like your T has issues surrounding this which could potentially negatively affect you.
