I would park at the CR if possible. The internal buses at FW can be aggravating.
We've been to the Hoop 4 times, and have our 5th scheduled for October. I guess there are people out there who think we are crazy, but it is really fun for us. It keeps the kids occupied while we get to eat!
Also, if you have any food requests (vegetarian, etc) be sure to tell them a few days ahead and they'll make up something special for you. Also, if your kids might want something other than the regular fare, they can whip something up for them as well. Just tell them ahead of time so they can prepare! We love the regular fare that they serve, but they have accomodated special requests made by our family members over the years.
