WorldMark Las Vegas-Tropicana! I'm impressed and have stayed here quite a few times over the past several years.
Upon my recent stay on third floor (top floor).. I definitely was impressed by the layout and decor inside each room along with the comfort and appeal with the attention to detail. The kitchen is huge and cozy along with a nice living room and dining area and the laundry room etc. The fitness center is open 24/7 and fairly small with mainly cardio, and a small weight section. There is protected code needed to enter, but then give you the code up front next to the buttons.. which is sort of weird and not protected.. like what's the point of a code? There's also a pool for those looking to soak up the sun!
My only gripe with the timeshare (like all others) is the aggressiveness of WorldMark as I feel as they usually are pushy and call a bunch of times or slip notes under the door to promote their "meetings" to get you to upgrade and purchase more points. Minus a star for that!
Overall, a hidden gem just west of the Strip on Tropicana and perfect for vacationing when in Vegas.
