We stayed at POR AB room in November with our 13, 9, and 7 year old, and we were perfectly fine. I love how some people think that they need all this space to sleep for a week in a hotel room. Then again, I'd bet that the same people also have a bedroom for each kid, a family room, rec room, toyroom, and 5 acres of land, too, so I guess it is all relative. We are perfectly fine in our 3 bed, 1 1/2 bath 1400 sq foot house in the suburbs of Chicago, so I guess a 300 sq foot hotel room for a week doesn't bother us.
Since you have small children and I don't know how they do falling asleep to the TV or you and DH talking, etc, I would consider that as a factor in what room you choose. My kids are fine with all of that, and they were so tired from a day in the park, so no problems there!
Good luck planning!
