More info from
Instagram, this time about character meets and the rides: for both you can make reservations on the app once onboard. It says that there will be character meets without reservations as well and the rides will operate sometimes with and sometimes without reservations.
I think with that an early port arrival time will be important! But I also wonder how clued in the demographic on these cruises will be for the first year, a lot of people new to
DCL might not be aware of how you need to get reservations for things and so on.
