Tropicana is the completely undecorated pair of white towers at the south end of the strip near Mandalay/Luxor but on the other side of the street. While it's ugly on the outside, I've seen several reviews recently (Spring 2012) that have been very favorable from a service/amenities standpoint.
Their casino is also known to often have lower limit table games, so that's a bonus. They do have the dreaded resort fee so keep that in mind when comparing prices on rooms.
