If in concierge, yes you can. Normally if you book Palo or Remy on the first night you can book that restaurant for a second night during the cruise. But with concierge, you can book it multiple times. I have Remy booked twice for dinner and Palo twice for dinner, along with a Palo brunch on the one day I'm not doing either for dinner (a 5-night cruise). While we love
DCL, we are not the biggest fans of Disney MDR (I know I"m strange and a rarity), and with our Disney rewards points, what better way to use up those points than with Palo, Remy, and a cabana on
Castaway Cay. I should add that we have a great TA with
Dreams Unlimited and he made sure an email was sent to concierge with our requests at midnight on the first day our window opened. We were able to get everything we asked for.
I also see that you are sailing in a couple of weeks. If you have not booked for any of these restaurants then I would see the concierge desk once you board the ship and see if they can get you a few of the bookings you would like. While it's not guaranteed, I have no doubt they will be able to assist you with this.
