Yes, you can....I think there's a path, too.
Hope you get the 2100 & 1100 loops --- It might be worth a fax to FW Room Assigners 4 days before you get there, especially if there are 2 reservations--You can explain the situation, & from my experience, they do try to work it out. I find, also, that if you can check in early, that the front desk can change a cabin assignment, if available.
