Welcome!
Yes, you are Silver now so you can book your onboard activities and shore excursions on July 18th.
We will have to wait until we get closer to know what is going on with the Bermuda Authorization form. A few people who are on our sailing have called Disney and it maybe that they may take care of the Authorization form for us. Here’s hoping they do, but Disney phone CMs have been know to give out incorrect info. Disney hasn’t mentioned anything publicly about the Authorization form as of yet.
As of now everyone still needs to upload their Covid vaccination to safe passage and provide a negative Covid test also to safe passage when it comes time.
I have been occasionally checking Disney’s website for our sailing and looks like it is a pretty empty sailing. I am not surprised you were able to get moved to main dining. I wonder how many GTY rooms they have sold. We happen to be one of them that moved our stateroom to a GTY to save some money. Can’t see that info online to truly know how full our sailing is.
