Would have rated excellent....however...
I want to say that the service at this hotel is, for the most part, superb! However, we ran into a HUGE security issue. We were originally booked in room 1413. Our room seemed kind of small, with an oddly placed window, but manageable for a family of 2 adults, a teenager and an 8 year old. 
The Good:
The valet and bellmen are very friendly and great with kids, which helped make our first night in Ft. Worth fantastic! The front desk staff at this hotel are also very friendly and knowledgeable. The manager's reception is great. It's basically 2 hours of free snacks, beer, wine and a full liquor bar. Again, the staff running the manager's reception were great! The hotel's location to Sundance Square can't be beat. There are tons of fantastic dinning options that are all within walking distance. 
We ended up spending the early part of day 2 in Dallas at the aquarium. (I highly recommend the Dallas Aquarium!!!) We planned to spend the other part of the day touring Sundance Square.
The Bad:
Unfortunately, in the late part of Saturday afternoon, we found out that the lock on the door to our room was malfunctioning. It turns out that our door hadn't actually locked since we had checked in on Friday afternoon. You could easily walk into our room without a key. Essentially, my family was sleeping in an unsecured room and didn't know it. It's something that we should have checked right when we got to our room..but we didn't. After a very long drive with our 15 year old teenage daughter and 8 year old son, all my wife and I wanted to do was hit the Manager's reception then have dinner. The last thing we were thinking about was whether or not our room was secure.
Once we realized that our door wouldn't lock properly, we notified the front desk. They sent up an engineer within 10 minutes. He informed us of the nature of the malfunction. You could unlock the door with our key card, however you needed to re-insert the card in order to lock the door. Otherwise the door would not automatically lock once it was closed. THIS IS A HUGE SECURITY ISSUE!!! Once we were inside the room, we couldn't lock it and we were unaware of it. We thought we were perfectly safe. The dead bolt didn't even work.
We decided that a visit to the front desk was in order. We notified Laura of the situation. Laura essentially saved our weekend with her empathy and professionalism. She was as horrified as we were at the lack of security. She promptly jumped into action. She comped our first night's stay and relocated us to room 1410. That was when I realized how small our original room was!! 1410 is the type of room i'm used to staying in at Embassy Suites! Our original room was cramped by comparison. I'm still wondering why I was initially booked in a smaller than average room (with a malfunctioning lock)??
Will I stay in Fort Worth again? Absolutely! Will I stay at the Embassy Suites? I'm not so sure. The staff is fantastic but the security seemed to be lacking.
