Charlie,
I have 2 mounted orchids that I take on any extended vacation where I'm
not flying. I've done this several times and have had good luck doing this. I
know certain conditions vary (Where you are staying, etc
but if you don't
mind and have the room, bring the "kids" on vacation with you. Both of your
mounts are orchids that probably won't mind drying out somewhat without
any seroius harm. So it's up to you.
