nannette and jenneth, BWI is wonderful! We love BC and BWI for different reasons, and we really enjoyed our split between BWI/Dream Cruise/BC last summer. We're trying YC and POFQ this spring (Easter week - crazy rates - time to try a new moderate!) but we're definitely working both BC and BWI into our plans for 2013. Yay for split stays!
I highly recommend a Boardwalk view - the proximity to the water is amazing and we could see MK fireworks from our balcony (and Illuminations fireworks from the club lounge!) The Boardwalk view rooms are lively (but not too loud) at night and completely peaceful and relaxing in the morning. I was so happily surprised by how tranquil it was in the morning - one of my favorite WDW resort rooms ever!
And I don't like clowns, but that slide doesn't bother me one bit - I love it (and I'm generally not a fan of waterslides, so that means a lot coming from me!) It was a ton of fun and we had a great time. The Luna Park pool is a little more crowded than SAB simply because Luna Park isn't as big, but it wasn't uncomfortable and great for a quick afternoon swim.
There are a few other differences, like the lobby (prefer BC) and the refill mug situation at BWI (no self-serve stations at BWI, but we resolved that by booking CL!) As reported elsewhere, the CL CMs are outstanding and the lounge is very comfy. While our boys prefer the food at BC CL (hard boiled eggs for our 12-year-old, swedish fish for all, and plain rolls for our 11-year-old!), we all loved BWI CL, too.
So BC fans planning a BWI/BWV stay - enjoy! (And be sure to check out
KOOK's great new BWI thread!)
