We just got back from 10 days at the CR bay view tower room. There was 6 of us

3 Adults DS13, DD10, DS2 (porta crib). And we really had room believe it or not. Yes we were a little tight but it was manageable. We really were only there to sleep...so it wasn't that big of a deal.
I had 2nd guesses with staying there before our trip. I always wanted to stay there and so did my kids. After reading opinions, I was getting scared. But we absolutely loved it. I would definitely go with the tower room with kids. In a matter of minutes we were out of our room and on the monorail. I will never do a non-monorail while I still have to deal with a stroller. When we did the bus to MGM...it's a pain to break everything down, carrying bags...and if you don't get a seat ahhh

(especially at night). I know people think the Contemporary is far from the Disney theme...but my family highly disagrees; however, everyone has different tastes...that's why Disney made so many different kinds of places.
My suggestion...go with what your gut says and what is most important for you and your family. Bigger rooms? monorail access? beautiful grounds? more themed? I think I would of been highly disappointed if I hadn't gone with my gut and our initial wants on our trip.
Again...just one of many opinions...just remember it's your trip and yours alone...take suggestions into consideration, but if you had an original resort in mind, go with your initial feeling. Switching back and forth can make a great planning experience feel like a bummer.
Pixie dust to all...
