Igloo

Introduced in The Sims: Vacation, igloos are one of the lodging options available on Vacation Island. In the default lots, igloos will be found in the snowy area.

Igloos rent for 79 simoleons a night, and two Sims can sleep in one. When Sims who are sleeping in an igloo wake up, they automatically change into the appropriate clothing for the area of Vacation Island they're in. Just having a hotel key doesn't allow Sims to use igloos, but Sims that have hotel keys can rent them. While Rental Shack Zack talks of "checking out" when an igloo is rented, what appears to happen is that the rental expires at 11:00 AM.
