The only loop with both is loop 100. The cabins in the 100 loop are reserved for special folks I hear, but we got our daughter in there once with the grandbabies, but we were across the street in loop 400. Not sure what he real scoop is for these cabins.
Very cool if you can all get in loop 100, but don't get your hopes up, IMHO.
The hot set up is to call FW front desk no more than four or five days before you arrive. More advanced than this and they don't have your ressies from CRO. we were told. and don't know who you are. Start giving them the pitch and see what happens.
This would be very cool and I hope you can pull it off.
