We drove to Arkansas from Oklahoma a few days later only to have the clerk tell me she was watching for me, because she had been told I could not use my letter that way and refused us rooms even though I had confirmation numbers for each room. I called back after inviting our friends and I ask one more time with another representative, if they would indeed let us use the rooms with different people on the same night and she said of course, no problem at all. They didn't care who stayed in the rooms. The hotel answering staff said of course that's fine.
I could not stay two nights so I thought what the heck, I'd call and see if we could bring friends with us the same night. I got a letter that said I had 2 free rooms, not to be used the same night but could be used consecutive nights.
