I will try and help a bit, if I can. I have stayed in a 2 queen room Atrium CL, 2 queen room Tower CL & a king room Tower CL. Both the queen rooms were Bay Lake view and the king was MK view.
I'll start by saying that I LOVE CR CL for our family! We have had ups and downs on our stays but the CL staff and the hotel have always been fantastic!
With the Tower queen room, there was no day bead but the room itself felt much bigger and was beautiful! The balcony, as
@GADisneyDad14 said, is HUGE, and really adds to the spacious feel. The bathrooms do have glass shower doors and only 1 sink but there is so much more storage and it is set up much better. If you are worried about privacy, you could clip a towel to the shower door.
The food is the same in both lounges, for the most part, with a few minor additions in Tower. Also, the drinks have a few extras in Tower as well. The Tower lounge itself is incredibly relaxing & quiet.
I guess you can probably tell, but I would definitely vote for Tower CL. I will try and dig up some pics of both rooms & lounges for you...hope that helps a bit.
