Not yet, waiting on Disney to confirm. We put in the earliest date for planning.
If you booked in the block it will change with us. Please wait to book your flight until AFTER we have the set in stone date from Disney. If you booked on your own you can change it any time you want until 31 days before the event. There's not a fee imposed to make the change until 30 days or less. Either way, any fast passes and non-party related meal reservations need to be changed by you.
Other than the reception time we have to play it by ear. Disney will have us doing photo shoots and such and we cannot promise much one on one time. However, we will do our best!
Short of Covid-19 related cancellations, flights generally are NOT refundable. If you booked with the party and cancel 45 days BEFORE arrival, you get all but the deposit back. If you booked on your own you can cancel 31 days BEFORE arrival and get it all back. In either case, if you cancel after those deadlines you may not get a refund. Please be sure you read the terms that get emailed to you when you book.
