Lol - oh no, so many choices! I fear you've tagged the wrong people if you want a fair opinion lol.
In all honesty, this might surprise you, but if it were just DH and I going to WDW for a weekend, I might go with BC (or even YC). Reason being we'd want to hang out probably in Epcot the most....we love the countries for snacks, drinks, and meals. We love to stroll around the boardwalk too. If just for a weekend, I can actually see us only going to Epcot and hanging out at the resort. BC is perfect for this.
With Poly CL being our favorite, I believe it's partly due to the conveniences it has for us as a family. Everything is compact and close-by, so my girls can have some freedom to come and go a bit. The lounge is so laid back with lots of kids (and some messes it seems, lol). Perfect for families. On the other hand, with BC CL being a bit more formal and polished, I think DH and I would enjoy soaking that in.
Now that you mention it, since the WL lounge is brand new (and did you see
@GADisneyDad14's pics?!), that might be perfect for a getaway! My holdback is I really didn't like the rooms too much for our family of 4. But for just DH and I, it might be perfect! Only thought is it wouldn't be so easy to hang out at Epcot each day/night so staying at WL wouldn't be nearly as convenient as BC.
So I guess my vote goes to BC, surprisingly, as you know how much I love Poly CL. If it were longer than a weekend trip, I might vote differently.
Oh pas130 - we are trying SL over Easter break! It has been a rough decision with lots of changes, but I think my final decision has been made. First AKL CL, then moving to GF SL. Can't wait!
Happy planning!!
