Encontrei muitas referências a 'hostel prison', tanto em sites norte-americanos quanto em ingleses:

Consideration should be given to abolishing the term ‘Resettlement Prison’ since it is a
function of all prisons. The title ‘Hostel Prison’ is suggested to indicate its bridging
function clearly, and give some reassurance that it is still a prison. Advantage should be
taken of such an investment by flexible use according to need rather than age or other
label, and they should be adapted and adopted on a Regional basis.

I heard it is a felony to cheat in a casino in Nevada, even at a $5 blackjack game. True? Kenneth K.

Be it $5 or $5,000, cheating in a casino is a felony punishable by up to 10 years in a rudimentary Nevada hostel-prison. Cheating is one mistake that a misinformed player who romantically envisions himself as a cagey cat should avoid. Most, if not all, casinos will prosecute to the full extent of the law.

acho que já vi isso utilizado aqui nos EUA
