We are on that cruise too! One way (and sorry, it's kind of sneaky) to see what your cabin looks like is to go to travelocity.com and pretend that you are booking a cruise on our ship - it show what you cabin looks like and what they still have available. It also lists the categories - I think with an 8A you are on the upper deck - is that right?
I discovered this method while I was reseaching cruises and prices.......
Hope to see you on the Triumph!
