Just FYI, the threads were merged because it's the same topic.
I really don't know what to advise, because of the 2 week vacation. Without food or water for two weeks, she may move along.
And with some nut out there, I'd be worried because of that too!
On the other had, she would need to see a vet before being brought into your home, even if she were going to be separated from your other kitties. And with someone else caring for the cats, there's no guarantee she won't escape her room - and if she has litter box issues, is the person caring for your kitties willing to deal with that for two weeks? It's a really tough position.
When we rescued Billy, he had giardia. We had no way to separate him from our gang, and we could NOT risk having them get infected with the parasite. The treatment is 10 days, and we wanted fecal samples over several days to ensure it was gone (one fecal sample after completing the meds is not enough). So when we brought him to the vet, if he hadn't been neutered already (we'd already trapped him and had him neutered and then released him - why he's inside now is a long story), we would have had him neutered, and then poor thing had to stay in boarding at the vet until we were sure the Giardia was gone. He was there just shy of two weeks.
Is getting her to the vet before you leave on vacation a possibility? And do they have boarding? Would they keep her for the two weeks you're gone? It is certainly not ideal - but she could be spayed (if she's not), vaccinated, treated for worms or any other parasites or illnesses she's got by the staff - tip them generously and ask them to keep an eye on her and interact with her if she'll allow it - and then bring her home when you're back? We bought Billy a carrier and cat bed, and the vet place put it in the cage with him, so he at least had a kind of hidey place. We handed off Feliway and asked them to give the carrier a spritz every three days.
When we came home, he was SO HAPPY to be out of the vet, that he became a love pretty quickly - so the long confinement at the vet facility sometimes has its advantages when it comes to socializing.
I'm pretty sure that's what we would do in your situation. I don't know what else to recommend.
