I spent 5 nights at the the Las Colinas Resort Hotel on business, the facilities are first class and can accommodate literally hundreds of people (@280 in the group I was with).
The room was good without being exceptional, the facilities, spa, gym excellent. The hotel catered for over 300 people in total without a hitch, food was varied and cooked to perfection, lunch and evening meals.
The staff were friendly, professional so much so you didn't know they were there unless you wanted them. Golfing facilities first class and as always the weather was good.
