1. What are the small (or big) differences from one hotel tier in Vegas to another (without bashing any property)? For example, NYNY is 4 stars while Luxor is 3 stars but what do you think accounts for those differences? 2. And as a side note, do you think that the tier system in Vegas is on-par with other cities (or might the low tier and perhaps even the higher tier be a higher/lower standard than other cities?) For example, Luxor may be 3 stars in Vegas but would it be 3 stars in another city, considering it is a massive resort?
