A very nice stay!
I accompanied my husband to Dallas for a business trip and we spent 2 nights at the Intercontinental. I was left at the hotel without a vehicle for 1 day while my hubby was at work. 
We utilized the free self parking option and carried our own bags into the hotel. The lobby is huge and contains a Starbucks and a few small shops as well as a bar and a full service restaurant. Check in was friendly quick and easy. The hotel does require a $50 per night extra refundable charge to your credit card during your stay for room service, wi-fi, etc. that seemed really excessive to me. 
There always seemed to be an elevator waiting. Our 6th floor non-smoking room was clean, spacious, and nicely decorated. The shower was adequate and the bed was comfortable. We heard no hallway noise. There was not a huge selection of television channels, but I always found something to watch. There was an issue with our toilet after a housekeeping visit. The toilet would not stop running. It was not a big deal for us as we were really only there to sleep that night, but I could see it being an issue for others.
I utilized the hotels free shuttle for a visit to the Galleria and really found that service to be a big plus since I was at the hotel with no vehicle and the selections at the hotel for food were typical 4* hotel prices. The driver was friendly and the wait was not long.
The wi-fi charges are per device so with 2 online adults we spent $20 a day for wi-fi. Really?
Overall it was okay, and we got a good deal on Priceline for our stay.
