Stayed here for a conference. They took a while to get the room ready, but they took my luggage and we all left to go about our business, and they called us when they were ready, which was nice. I ended up trying to go to the wrong room because I couldn't read the desk agent's writing, but someone came to help me out and take me to the right place and they were very pleasant about it, which is rare these days!
The rooms themselves were more than adequate and spacious enough, but they weren't particularly thrilling. I wasn't expecting anything scintillating for this conference though, so it actually exceeded expectations. I wish the TVs were flat screen. But the rooms were very clean, the beds comfortable, and the housekeeping leaves you nice chocolates on the bed and make up your room at night (turn down service). The front desk agent was very helpful about getting me a map when I needed to drive somewhere and even let me behind the counter so I could input directions myself into Mapquest.
I joined their free loyalty program and got free internet and goodies delivered to the room. Also, I banked my three company-paid nights towards a free night at a different Omni for my personal enjoyment :)
