I would give this service 5 stars, but my followers know that my review policy requires that I use a company multiple times for that.
We travel annually to Las Vegas, and we have found over the years that The Signature at MGM Grand is our favorite place to stay. Until this year, we have contracted directly with the homeowner or the hotel to arrange accommodations, but this year we decided to try Las Vegas Suites because their rates were so much lower.
Usually we've found that the old saying "You get what you pay for" holds true for us, but we decided to give them a try because the discount was deep. With the exception of no daily cleaning (which is available, but which we didn't need) we didn't notice a perceptible difference in booking EXCEPT the customer service was better with Las Vegas Suites. Same room, same finish level, same everything.
From reservation to check-in to receiving our damage deposit back, our experience with Las Vegas Suites was professional. Add to that the substantial savings and you can see why I would recommend using their services.
BTW, they also represent many other facilities - not just The Signature.
RECOMMENDED: For anyone traveling to Las Vegas who wants to get a bigger bang for the buck on accommodations AND doesn't want to sacrifice customer service.
