Thanks for the review Jackie - the walk to the MGM is not part of allure of the MGM Signature. The fact of the matter is that the MGM Signature is a 5-star hotel that is connected to the MGM and targeted for folks that want to get away from the sound of the casino and spend quality time in a truly beautiful resort.
Also - in our house rules, we make it very clear that daily housekeeping is not included. That's why are prices are 40-50% lower than the Signature's pricing.
Lastly, since you're subletting a unit that I own, the reservation is under my name. This is the equivalent of someone renting your room and not having to tell the landlord that they're doing it because they are not obligated to do so.
