Hi, the cruise rates does go down in Sept. I am guessing you both will have to pay $100. more each for a cat.4-A.
If you want to change..... tell your roomie that the ship really goes up and down a lot way in the front of the ship. IT REALLY DOES!!! She may get seasick and not like the bouncing of the waves. It feels like it is hitting a brick wall.
The front of the ship is the last place I want to be because the cabin has too much movement. The port hole cabins are nice but I don't think they are worth it to me if they go up and down too much.
There is still time for you to move to a mid-ship or AFT cabin. Lucy
