If you haven't already, you could try replacing the night time feeds with bottle feeds and you pump during the feeding. After the interview, you can go back to regular night feeds if you want.
Depending on how old your child is, if you night wean your child will likely start getting enough calories during the day instead. We actually decided to night wean when we realized kiddo was getting something like 90% of calories at night- clearly capable of getting all those calories in a 12 hour period, so we just needed to switch which 12 hour period it was. (kiddo was around 8mo, I believe) Just for the record, there's a 6 am feed that we still haven't been able to phase out- kiddo can't go all the way from bedtime to breakfast time without food, and the same could definitely happen with your baby.
Your baby is younger than ours was, but you can still nudge it if you want to. I would not do a total one at all, that seems cruel, but you can do it gently so the child doesn't suffer. Just nudge it slightly so that your baby isn't eating as much at night, so needs to eat a little more during the day, and eventually will be eating everything during the day (hopefully). There's a lot of advice on how to night wean from breastfeeding and I'm sure you can find advice that works for you. "The No Cry Sleep Solution" is also a very helpful book on how to adjust sleeping routines without CIO.
It's your call if you actually want to night wean or not, though, if your baby will take a bottle instead of a night feed, that may be an easier adjustment for both of you. It doesn't sound like you want to night wean over all, it sounds like you still enjoy the night feedings.
Have you looked up advice on traveling with breastmilk? You'll need to bring a cooler, pump, etc. If you have to fly, you'll want to look up airline regulations (you're allowed to bring breastmilk on, but some airline employees may give you crap- so if you know your rights, it'll be easier) and how best to deal with it.
this is just a moment in time, step aside and let it happen
