I decided to give the The Grand Spa one last try during a recent 3 night stay over Halloween weekend 2014. During my two previous visits (November 2013 and March 2014) the steam room wasn't functioning and the staff were inattentive.
The past few times I've visited the quality, service and amenities continue to decline. I've enjoyed the Grand Spa on several trips. I vacation at MGM Grand multiple times a year.
