Things we loved:
The price for our 2-bedroom suite for a week. Awesome!
How quickly we got a response while booking/before we were booked.
Things we didn't love:
The room was generally pretty worn
Smelled like Cigarette Smoke
Broken/ripped chairs and very little glassware
(we actually immediately took photos, an inventory, and e-mailed them to let them know since we have read reviews where they charge people for things they didn't break).
You cannot call down for valet ahead of time (you can't reach the valet from the phone) which is rough when you're trying to get places/have lots of items you're toting around.
Once we got there it was very difficult to reach LVS with questions
All-in-all it was fine, we got a good rate for the room and we liked that! But, having stayed at the signature suites before through the hotel you can definitely tell a difference in the rooms and service.
