Because of a pandemic. It is far more important to us to have everyone be able to celebrate with us than to push for a wedding that may be threatening to the health of attendees.
Hopefully your airline will be flexible and you can just push those flights to March 2020. We received an email from Marriott stating that they would offer cancellations for hotel rooms booked, as long as they were cancelled by April 30, 2020. So you have time to change that reservation and get your money back.
Yes! Your little babies, toddlers, and family members who act like children are all welcome to the wedding ceremony and reception.
