First and foremost, congratulations on both counts!! You deserve a cruise! <grin>
Do not worry about your accomodations. You will be fine and have a wonderful vacation. You will not be spending a lot of time in your stateroom anyway. Typically, the deals are better on the inside cabins, and many chose those and invest the difference in other activities.
There has been much written about room location. In my opinion, there is very little difference, particularly on a ship as huge as the Grand. We were in the last cabin aft last year and almost all the way forward this year, and I could tell no difference in movement.
Have a fanastic voyage. I look forward to your observations when you return.
