Stayed just one night at the Omni to attend a concert at the arena that is connected to the hotel. Terrible experience. There does not appear to be ANY sound blocking between the hallway and the rooms. People just walking by and having conversation could be heard clear-as-day in the rooms. We had trouble going to sleep because of hall-way noise, and then woke up MUCH earlier than we wanted to because of all the people walking by and talking. It almost feels like it is amplified in to your room! So after NOT getting to sleep in like we wanted, I made a cup of tea with the in-room coffee maker. My friend doesn't drink coffee or tea - so this was the first use during the stay. My tea tasted like coffee, so I checked the coffee maker and the filter-pack had been left in the coffee maker from the previous guest. GROSS! Last complaint: the inside shower curtain was not just dirty, it looked nasty. Not moldy or anything, but it really needed to be retired.
The good: nice location, staff seemed nice, nice amenities. The bed was comfy - just wish we could have slept in.
Seriously - other hotels exist in the area, probably much cheaper. If you want to sleep, find another hotel. We paid $230 for the night and got about 6 hours of sleep at best because of the noise. If I had been there for longer than a night, I would have left and found another place to stay.
