Hi m.l.
We sailed on the Dawn in March and had an oceanview room (no balcony) on deck 5 also. Our room was really nice, but pretty cramped with four of us (my husband, me, and our 5 and 2 year old boys). When we arrived, the room looked spacious . . . 2 twin beds set apart (looking like couches ) by the window. As I recall, there was also a chair or two at the vanity on one side of the room and another chair or stool near a small table on the other side of the room. Once they made up the beds for the first time, however, (pushing the two twins together to form a big bed for us), the space was eaten up. They left the beds in that position for the rest of the cruise, which made seating really cramped. Our older boy slept on an upper bunk which pulled down (and then went back up during the day) and that was great. But our two year old slept on a trundle cot which pulled out from under one of the twins. His bed was directly next to ours making it one gigantic bed and therefore eating up all of the floor space at night.
I don't want to sound too negative, tho. It was still a really nice room (much better than we expected), and the cruise was so fun that we really spent very little time in our room. I think on our next cruise, however, we may invest in a 'mini-suite' - so we can spread out a little.
Anyhow, I hope this is helpful. . .
Have fun on your cruise, and don't worry about the anti-kid sentiments you found elsewhere. There were over 200 kids on our ship, and all the non-kid folks we met were very kind to us and did not seem mind sharing the ship. (I did have a similar experience to yours on our plane trip home, however, where the woman behind me ranted throughout the flight about the number of children on the plane and how it was unfair that she had to pay all that money to hear kids crying and fussing. She really got my blood pressure up . . . especially since we also paid good money for our kids' seats on that plane and they had as much right to be there as her. Though I wanted to tell her off, I held my tongue because I suspect she is just a mean spirited person and my words would have done little to persuade her

I agree with the others that anyone looking for an adults only vacation should go to an adults-only resort/ship. Cruise lines now cater specifically to families with children . . . they want you and your kids there spending money. Don't feel guilty! Have fun with your baby. Its a great family vacation!!!
Good luck!!
