Sure have. My wife and I had our wedding there 3 years ago. We only had breakfast on the day we were leaving. I don't remember much about it, which if you knew me, is a good thing. Similar to Hilton breakfasts. I think eggs to order and then standard breakfast buffet (cereals, muffins, bacon, sausage, pancakes, juices, etc.) is the arrangement. Sorry, I am kind of sketchy. It was a chaotic weekend.
It's a great hotel though. If I remember correctly, it was around 10 minutes to the WDW archway that greets you driving in.
The hotel itself is quite nice. The rooms are all what I call "executive" meaning they have a sitting area and the main thing I remember was that my wife appreciated the ample space in the bathroom for all her "stuff".
The beds are comfy, nice furniture and appointing. The pool area is nice and quiet. Lazy river seemed cool, though we didn't try it out.
The staff there is awesome, and the sports grill (David's?)serves very good food.
Convenient Publix & Walgreens/CVS right outside the gates.
I thought it was pretty convenient to WDW, and actually remarked to my wife that I wished we had just stayed there after I saw how short the drive was. Omni over a mod any day imo.
I would stay at Omni in a heartbeat if there was a good rate.
