I was pleasantly surprised that I have a back-to-back of a 3 and 4 niter in late August for a guarantee inside (?) cabin thru Casino Royale. I needed to pay for a second passenger and taking my son as a birthday gift. The 3 niter, I was already assigned a CP view cabin. Waiting for my 4-niter assignment. My invoice simply says guarantee and wondering at what point I'll know of the cabin assignment.
