Staying at BWV and have an ADR at CG. Would like to head to the Tambu Lounge for a few drinks after (via the monorail), so don't particularly want to drive (but we will probably have a rental, so can).
From BWV take the bus to the Magic Kingdom and from there use the walkway to arrive at the Contemporary. If you have never been to the California Grill before check-in is on the 2nd floor of the Tower and from there they will take you up to the restaurant.
