My question is Will you use it? I had a Verandah in September in the Bahamas and only opened the door a few times. It was hot. (April would probably be lovely). It was probably a minimum price difference; also on the Dream.
As it is, I barely use the room. Sleep, shower, dress. A very little time relaxing in the bed.
Sounds like you will spend your time in the adult areas?
And good for you - using the stairs!
When you ask about paying more for something, do what your instincts say.
