Large apartment-style suites near the strip, but without the casino crowds. Feels no different than booking directly with Marriott, except no daily cleaning service, and not sure you get the points. If you're a Marriott member, probably the best option on the strip.
Ours was a large 850 sqft 1-bedroom villa, with full kitchen and (bonus!) a washer-dryer. Functional, comfortable, although certainly not opulent. Great for long stays, or if with family.
Not many food options in-hotel, but easy access to other hotels/resorts. Would definitely stay here again.
