Hello, Casey!
Congratulations on bringing your new little princess to Walt Disney World for the first time! As Disney Vacation Club Members, you'll have a lifetime of memories as you enjoy your membership together...take lots of pics!
You'll be happy to know, too, that there will be a pack-n-play in your DVC studio or villa; you can usually find this in the bedroom closet (master bedroom if you have a 1- or 2-bedroom villa.) Should you wish for something more substantial, be sure to ask at check-in if there are any cribs available. We've used both a pack-n-play and a crib from the resort while on our Disney vacations, and both were just fine for us. (The sheet for the pack-n-play, by the way, will be with the crib in the closet. No worries about bedding.)
Please send more questions as you think of them, including questions about your particular DVC resort, traveling WDW with an infant or any other facet of your trip. My first trip EVER to WDW was with my 5-month old son, so we learned through experience how very supportive of young families Disney can be! (Case in point: did you know that there is a
Baby Care Center in each park? What a great help!) I'd love to help make your first visit as a DVC family as magical as it can be! :-)
