We are DVC members too! We started off at WLV but sold those and now just hold the BCV ones (really tempted to add some on, though). Are you staying at WDW before or after? We are staying 5 nights post-cruise.
We are just staying the one night before the cruise... we snagged a Grand Villa at OKW... super excited to check them out. Wish we could stay longer but it had to be a quick trip for us this time.
We own at AKV and BLT... hope to try for BCV someday!
Are you planning any special birthday surprises? So excited that it falls on Castaway Cay day! How perfect is that?
