Wow!!! You should have some awesome views from that suite. As for motion, unless the seas are exceptionally rough, you should be comfortable and you will feel minimal movement. The new ships are now equipped with such excellent stabilizing systems that motion is seldom an issue.
BTW - I am putting the finishing touches on my mega-review of the Jewel, which you may find of help as you plan your trip (should be posted in a week to 10 days).
