Signature Suite is part of the MGM complex, so it is like you are staying on the resort itself. The only difference is that it is cheaper, but with more amenities. One remarkable feature is the kitchennet, with microwave, fridge, two cooking tops and all the necessary cooking utencils, although you may not need to touch them since you are right on the Las Vegas Strip. Alex and his team are very responsive, seems that they are right by your side. Communication was very fluent. The only pity is that the rate is relatively higher than expected. Of course the reason is that there's an exhibition going on and I booked it in the last minute. Try to avoid those dates.
