Hi, I am new to this board, and have booked on the Zaandam rooms 2509 and 2513. I have read that those rooms have alot of noise and feel the motion of the ship the most. Is that true, and should I try to get our rooms changed? My parents are in the other room, and they are 80 and 84 years old. Thank you in advance for any helpful information as to which rooms we should try to get.
