If you are looking for a place to stay on/near the Strip, the Signature is a contender for you. It is part of the MGM and so you get the benefits of using the MGM pool and you can get to the MGM (and the Strip) without having to go outside in the suffocating heat.
As for the booking process, it was a bit wonky to go through the property manager's orgoto.com's site via VRBO. Orgoto required a photo ID which is their own policy and not that of VRBO. As such, that aspect was a bit uncomfortable, though it worked out.
If you stay at the Signature towers, you may end up with a very useless bath towel. The towels are the worst we've seen: paper thin and they won't wrap around your body. You'd have better luck with a paper towel and a Q-tip. We made a trip to Walmart and got ourselves a couple of real towels. So, heads-up on that one.
Based on the categories provided, we are giving the property and property manager 5 stars. The location, description, cleanliness, check-in process, etc. were just fine.
