BWI or BWV? I've stayed at BWI twice.
Where to start on tips, the place is great, we loved it!
Can't misses:
BWBakery- everything there is yummy! Plus you can get healthy fruit and yogurts there too.
Luna Park Pool and Leaping Horse Libations- the pool is really neat, it has the Keister Coaster Slide and the lifeguards were really friendly with our kids. The pool bar is great, one time we were there we were sipping cold drinks watching the winter olympics in our bathing suits-surreal!
BW Buskers- some of our trips had cold and rainy nights so no outside entertainment but when they were out it was fun. Loved Carlo the Sword Swallower!

The entertainers will go out of their way to include kids.
ESPN Club- one of our favorite casual eating spots
Spoodles for breakfast.
Surrey bikes- never had so much fun or laughed so hard with my children and my crazy driver husband. I'm sure people thought we were nuts but we had fun!
I could go on and on but I'll let others chime in.
Have a great trip, wish I was going too!
