Close to blooming Paph and travel (also other plants)

[naturalistSean]

My wife would like to visit her family up in Germany for a week after Christmas and I've a few plants that I'm unsure what to do with. Of course Omicron may end the possibility of travel undoubtedly making the plants happier.

Of primary concern in this Paph. sukhakulii. This will be the first chance for me to see it blooming. What would give it a better chance? Traveling by car for 10 hours each way, and a week in conditions that are probably quite different, or leaving it here without getting watered for a week?

I've also a mounted Dendrobium tetragonum (not giganteum) that I've been unable to get to bloom. It recently finished growing two new psuedobulbs and has been very thirsty every day. I've been keeping it in a cooler stairwell. I'll almost certainly bring this along as it is very dry every morning and seems to require daily watering. Then again I've heard that they may benefit from a dryer winter period.

I've an oncidium that has been sitting with buds for a very long time. I'd have to bring this one too I think.

Probably my other plants will do reasonably well for a week considering that it is winter. Although I'm not enthusiastic about going on this trip one silver lining is that I'll be within a 40 minute drive to Schwerter.
