Okay. Looking at the pics, the color palettes still don't differ all that strongly to me. The floors are darker with good amounts of blue in both. Both have dark wood headboards. Both have white bedding with pastel-y foot coverings. I believe the day beds at Beach are pastel-y blue, right? That part isn't in the picture.

The wall paper at BW has more color involved. A big difference is the furniture pieces that are the "dresser" and present the television. The larger armoire appearance of the BW's piece has a larger scale. The smaller, lowboy dresser with wall-mounted television of the BC doesn't have as heavy a feel and doesn't seem to take up as much space in the room (height wise). It leaves things more open to me.
Just noticed! That Beach Club room pic looks like one of the smaller rooms. See the slanted line on the upper left side of the pic? Also, the furniture layout is different than others I've seen. The smaller rooms are a little different. The majority of the rooms are more akin to what we had at the Yacht Club. That little desk was situated between the 2nd bed & the patio. Across from the desk & 2nd bed is where the daybed was. I'd look for more room pics of the Beach Club to give you a better idea of the layout.
The tv positioning difference from the BC to the BW looks like maybe a foot or 2 of in relation to the ends of the beds. If it was just 2 people watching tv it's better to have the tv centered at the foot of one bed sorta like the BW pic. The tv in the BC pic seems to be more "friendly" for viewers relaxing in both beds as it looks like it splits the difference a little better.
Again, the overall decor differences are personal preference. If you tend to favor a more Victorian decor then probably you will lean towards the BW. Myself, I have almost an aversion to Victorian or Victorian-like decor because it feels gawdy, busy, and icky to me. My brain always gravitates towards simpler lines, lighter tones, and more airy, open decor. Neither of these decors are anything I would have in my home because even the BC has a little too much going on for my liking. Of the 2 I like the BC better but that's me. You should do what you like.
Still, if it's hotter months and I know I'll be cooling off by the pool daily I'm going to choose the better pool even if it means I don't like the decor of the room so much. Balcony? If it's hot outside I wouldn't be out there more than a minute or two before I was running for relief. I had many a nice drink by Stormalong Bay when we stayed at the YC. Definitely would love to take up that perch again.
If you are worried about getting a balcony at BW vs. BC's juliets you could always put in a room request for ground floor so you have a patio or for a true balcony room. For our YC stay we had a room request for a daybed room so the boys wouldn't have to share a bed and fight with each other. When you get there, regardless of what resort it is, if you don't like your balcony or room location you can always go back to the front desk to ask for a room change. They'll do it if they can.
