Well, I've only ever stayed at BRV. But I like that it's a separate building because it was really quiet. The walkway to the buses to was covered and didn't take long. The walk to the boat was a bit farther but it was a pleasant walk with nice scenery.
I really like the decor and the look of the rooms at BRV. Based on photos, CCV seem a bit "blah" to me.
At BRV, they don't have the massive, grand lobby. It's smaller but still cute. And there's a room off to the side that has a fireplace and chairs and whatnot. It's very cozy.
Staying at either, you can obviously still enjoy visiting the big lobby. And you can use both pools as well.
