My better half and I like the idea of long weekends / "staycations" in the off season here, but just staying in PHX is too boring. So we purchased a voucher from Deal Chicken (a Groupon-like site) for the Omni.
First off, everyone who works at the resort is very friendly but not in a stuffy way. They really seem to just want to make you feel comfortable and welcomed.
We stayed in one of the regular rooms (not the Haciendas) which are decorated very nicely. They are more spacious than a normal hotel room and really make you feel like you are treating yourself. Nice bed. Nice bathroom. They also have 2 robes hanging in the closet for you - love that.
We also visited the spa and got a couples massage. I am a total amateur with that sort of thing, but I thought it was quite nice.
We went to Legends for drinks one night and dinner the next. Again - the people were very nice. The prices are a bit excessive, but kind of what I would expect from a resort hotel bar. I don't really have anything positive or negative to say about the food.
The only issue we had was that there was a big storm when we were there and our room had a roof leak. We were switched to another room that also had a roof leak. We were offered to move again and just decided to stay put. When we told the front desk about the leak in the second room, he said that engineering would go take a look at it while we went to eat. Well - nothing of the sort happened because the place was still wet when we got back. It wasn't a big deal but I just like to not be told something that is not going to be done. Honestly, if they were REALLY on top of their game, they would have just offered to buy us a drink at the bar since I had said we were going there.
If we can get a similarly priced deal again in the future, I think we would go back.
