It won't make a difference for the reason you noted, except....
If you are sensitive to smoking and have a verandah stateroom:
On the Disney Wonder, smoking is ALLOWED ONLY
on Deck 9 FORWARD - Port Side - all day
and
on Deck 4 Starboard Side from 6:00 pm to 6:00 am
NOTE: on Deck 4 - ALL of it is NON smoking from 6:00 am to 6:00 pm.
If you have a DECK 8 verandah stateroom in the FORWARD area of the ship on the PORT side, many people have reported that the smoke and ashes will drift down onto your balcony, and sometimes the smoke will drift into your stateroom if the verandah door is open.
For this reason we chose a verandah that was Deck 8 Forward on the Starboard side. We had no issues.
Of course you also want to be aware of what is above, below and beside you when choosing a stateroom, as view isn't the only consideration - potential noise form things like the pool deck and theatres may be factors you wish to consider as well.
