Okay I've stayed here twice now so it's time to comment. Overall, I like the cabana suites but there are some pros and cons.
Pros: Very modern and comfortable rooms, beautiful decor, amazing lobby with freebies (water, candy), TVs, and a friendly staff. Price.
Cons: No view! The view is so unsightly that they painted a translucent stripe over the windows so you can see light but not focus on the outside. You have to walk outside from the El Cortez to get here and cross a street (but security is always there watching). Small rooms. Not much room to spread out here and no desk. Oh there's sort of a desk but trust me...when you see it you'll agree...that's not really a desk.
Having stayed twice, I'd certainly come back because the above cons don't bother me. I'm not in Vegas to sit at a desk or spread out or peer out my window. So I'm a fan. And as long as you're aware of the conditions I've listed above and you're okay with them, you'll enjoy the El Cortez Cabana Suites very much. The extra "service with a smile" really sets the whole place apart, in my opinion.
This is not my first choice, but it can be the right one depending on your budget and what you're looking for.
