MP, so you feel that you CAN get a proper initial dry completed before vacay..

However jarring up and leaving jarred up is still NO BUENO as there will still be moisture content trying to stabilize throughout the flower. Back in my very early days (many moons ago), I thought I had a perfect initial dry, felt dry, little crispy on edges (maybe even over dry). I jarred up, life happened and was unable to burp and stir for a few days, when I did get to it. wet funk...
That is all ANY of us are trying to keep from happening to you..
We get that you have high humidity and worried about leaving them out, however I believe that several have commented on that and the answer was to leave them in paper bag with some air movement (not directly on them, but around them) and you will be fine(even in high RH).
What can you change? Well it appears that you can NOT change the humidity while away. So the backup plan for me would be to brown bag it, hung up, small ventilation holes in paper bag with fan moving air around the bag. I would leave buds on branches to help mitigate drying out too fast. I would be comfortable with that.
I have no CLUE however a light bulb lit up, any information out on the web about any type of cold storage, freezing?
Hack it all down, low heat oven decarb, and dump it all in 1/2 gallon mason jars with everclear, put in freezer and you have the start of heaps of tincture.
not ideal, however just trying to think of ways so you dont loose 100%..
Now to just find something that you are comfortable with..
