Here's what you didn't know about Survivor's family visits.

According to this Survivor wiki , castaways have to pick two loved ones that they would like to come visit them: one as a main, and the other as a backup. Loved ones can be anyone, including a parent, grandparent, child, sibling, cousin, spouse, or friend.

No, they're not forced to build their own shelters. On Reddit , Erik Reichenbach-who appeared on Survivor: Micronesia and Survivor: Caramoan-explained that family members stay in a hotel before they appear on the show, and that "they stay on location a day or two." They head home right after the visit is over.

Some seasons have allowed family members to visit the camp, and even stay overnight, like in Survivor: Marquesas.

As Survivor films in locations that are a bit far from the continental U.S., family members often fly to the set while the previous episode is being filmed. As Erik further explained on Reddit, "[My brothers] flew to LA along with final 7 or 8 loved ones of people still left in the game. Then they flew to Palau, and Jason Siska was voted out once loved ones reached Palau hotel. She (Jason's mom) immediately was flown home & remaining loved ones met Survivors on show."

Yikes-so basically, you'll immediately fly home if your castaway is eliminated before the family visit.
