I recently got off the EB Transatlantic this year. We were all adults in our group. It was an amazing cruise, you will love it.
To reiterate, make sure you have the
DCL Navigator app downloaded on you phone before you cruise.
While it is more advantageous to book your activities and meals at your online booking time, there may be slots, especially for Palo and Remy, held back so you can book them as soon as you board. Also, tastings, which may be sold out by the time you can book them, may also be added and available once you board.
Dinner at Remy's was amazing. Fortunately, you will have many days to choose from to book. Same with Palo. Since there are so many sea days, Palo Brunch should be readily available online, but if not, once your board.
Certain Spa activities can be booked ahead of time, others may have to be booked onboard.
Our TA sailing was not full, so there were plenty of opportunities for all those activities.
I'm writing a trip report if you want to read about our experience
here.
Have a great cruise!
