Just noticed for my Christmas sailing on Wonder that several shore excursions are available to purchase now through the app. Just as if on board the blue reserve now radio button is highlighted instead of being grayed out. From there it takes you to select guests. Since my credit card number appeared I didn't go any further than that to see if it would actually work.it was not sll if yje excursions, just a few that had this option. Either testing or a mistake.
Just went back in and specidlty dining is also available to book.
It foes change your card on file. Just booked dining for Christmas day.
