[50][speculation] Were the pre jurors in ponderosa with the jurors until the day of FTC or were they moved to a different location after the pre jury phase ended?

With the exception of Q, Mike W and Kyle, the cast stayed on Fiji for the entire season. The pre jurors went back home on the day of FTC, so were they at Ponderosa with the jurors until the day of FTC, or did they get moved to a different location after the pre jury phase ended?
