I just heard about the Tropicana Las Vegas having to close some of the rooms in the Paradise tower section on Thursday because of some historical renovations not being up to building code.

The Paradise Tower section is one of three sections of the Tropicana Las Vegas. The other two sections were unaffected by this.
In a statement written by the company it says that the rooms that are affected by this will remain closed until the problems can be corrected. They don't give any time estimate for it to be complete.
