To begin with I loved staying at the Signature. The staff is incredibly helpful and offer great customer service. They have a state-of-the-art gym that is well-maintained with all the amenities you expect in a high-end gym. It is within walking distance of the strip and it is extremely easy to get UBER/Lyft right at the front entrance to the tower. A big benefit is the short walk from the lobby to elevators to your room/suite. And need I mention that the building is smoke-free so you don't have to deal with that! The place is well-maintained, clean, and immaculate. It felt very safe.
Lee's unit has amazing views. I had seen great views when I stayed at The Cosmopolitan but Lee's unit has great views even from the bedroom and is bigger with more space than the studio suite at the Cosmo (not to mention a full kitchen). The unit was clean with plenty of towels and no amenity was lacking. There were just two of us staying and we had one bathroom each because the unit had two bathrooms which is always great. We went to the ABC store at the nearby Miracle Mile shops and stocked up on items such as wine and food which is a lot less expensive than buying inside casino or gift shop. I wish the TV had the ability to do Netflix and other streaming channels but that's not the case as it has the standard TV/pay-movie interface that you see in a hotel room. But then why watch TV when you are in Vegas - you should be going out and living it up!
We were lucky to have booked the suite for New Year's eve and we saw amazing fireworks show with the fireworks fired off the rooftops of nearby Planet Hollywood, Aria and Caesar's Palace casinos. The 8 minute show was super spectacular. For sure our next Vegas stay will be at the Signature and specifically Lee's unit if it is available.
