Where is the hosting list or where models and MUAs can stay?

there is none on MM

if you need a host in an area you or others are traveling too,
inquire with resident photographers/models/local craigslist

otherwise ~ suggest searching www.CouchSurfer.com
where they can check references and set up their own schedule

otherwise: you may want to offer compensation (travel & hotel expenses)
for whatever project you may be working on at the time, if you do not desire
nor cannot provide hosting yourself.

There was one that Aubry/Vyl8 managed. I think it was in General Industry, but I don't recall seeing it in a while.

Maybe PM her?

There are also some model networking groups on Facebook that would be worth looking into.

^BOOM.

I will note it's sometimes outdated, but I have found it useful so many times still!
