Hi Mickie and welcome to the site. To answer your question about the impression of Eloise being the main focus, here are my thoughts.
In any articles that I have read about the missing couple, the focus was on Eloise, her dental business, her activities, her turtle. Perry's name was mentioned more in the background. Nothing identifiable about this man, other than he came from China. (Which turned out not to be the full truth).
On a positive note the question is perhaps they just decided to take a vacation, and not tell anyone?
It has been emphasized by staff that they would let their staff know weeks in advance if they were taking a vacation (if the articles are correct).
It gives one pause for thought, when no one has heard from them, and according to police, as far as they can tell - there is no activity in their bank account.
So, where are they? Did something happen to them? (hopeful not)
