Westworld question maybe someone can answer

Not sure how we feel about non-TV info here, so I'll post this as a link instead of an image, but the Delores story loop posted on the Delos site is probably the best insight into how the loops work: LINK (it's just an animated gif at the link).

Her normal story loop starts and ends with "new day at the ranch." I'd imagine it's similar for all the hosts, like Teddy riding in on the train every day before he was given his new back story.

I would guess they would run sessions where guests get to stay there for a week or so. Then when the session is over the guests have to leave and pay again if they want to stay. That's when they'd reset the loop.
