No specific e-mails, but lot's of information regarding vaccine and test requirements. I was in the same dilemma, as we had lifted and shifted a cancelled cruise to Easter 2022. At that time, there was no requirements for vaccine for children, however, this subsequently changed. I had one granddaughter that was 8 years old and no vaccine required, but my other 2 granddaughters are older than 12 and not vaccinated and were not planning on getting vaxxed. I was advised that I can only take action when the H&S protocols was announced which was at the 30 days mark.
Called my TA and advised that we are all ready and able to sail, but because of certain requirements, Royal/CDC will not allow these individuals and parents to sail. I asked that a refund be initiated as any FCCs would be worthless under these circumstances and expiration dates. Got most of the refunds to my CC within 45 days. There was a balance of approximately $1,200 in FCCs which my TA is in the process of transferring them to my name, as I have no problems cruising.
Ps. On June 1, 2022, Royal announced that any FCCs issued under the CWC will not have an expiration date.
