Worth a 3.5, but hey... that options isn't available.
When it comes to Vegas hotels it seems like it'll come down to your preference of style and how much you're willing to pay of course. THEhotel is a very modern and new hotel. If you want your modern styling with granite counters, dark woods, etc... this is a good choice. Unlike some hotels, these suites are "real" suites with separated rooms. The bathroom is also very large and has a TV (sometimes it's useful). The powder room out toward the entrance is also handy when you don't want people seeing the mess you've created.
The service is what drops this place down to a 3. Between our group we had 3 rooms, so this is the combined whining of all three rooms. An ash tray took over 90 minutes to be delivered. Room service took close the same amount of time. And a shard of glass was found in one bathroom (perhaps some partiers dropped a bottle), but you'd expect that cleaned up.
Overall... might be worth another visit just for the amenities and the modern styling, but... I'll definitely hesitate before I click confirm.
