@Don--Cindy--Patrick-And-0 since you already flat out asked the question and she skirted it, then you're best bet may be upbeat optimism (faked tho it may be)
"So glad you've arrived, hope the place is to your liking!!! Looks like some extra folks have joined you, I'm happy to come right over and get yall setup with everything you need to be comfortable. Be there in 20!"
And then go from there. Honestly, can't tell from what you wrote if they're "staying" or "visiting" and this is the bane of many a host's existence. People coming to visit family can be tricky in managing expectations.
Let us know what happens!
