Welcome to CC.
You can cancel (refunded to your CC) any planner purchase up to about 2 days before sailing - if you cancel the same thing on board, you'll get OBC.
One of the "substitute" Dreamers before you got on was pretty good too, though I told him to stick to singing when he was on the Flowrider.😇
Biker, who has also seen them on both Voyager and Anthem.
Again, if the web site fare you saw is a restricted fare, like new bookings only, they could be quoting you the next up fare without restrictions. @Ourusualbeach can perhaps provide some insight.
