Great plan, Kathleen!
You will absolutely love dining at
Palo on the
Disney Wonder. It is my absolute favorite restaurant! If you can, I would highly suggest getting brunch reservations in addition to your romantic dinner plans. They are both very different gastronomic experiences, and you and your better half would definitely enjoy either... and better yet, both! Brunch will be available during a sea day, and offers an array of gourmet choices, that are not available at any other time or anywhere else.
Schedules might still change, but usually, the 2nd night happens to be the optional dress up night (formal). On the 5-night cruises, Pirate night would be on the 4th evening. Hopefully, you can snag a dinner reservation that fits your preferences. To be on the safe side, check the Personal Navigator once you embark or double check with Guest Services, for the most updated information. If it so happens that you'd like to make a schedule or reservation change, you can always speak to the Palo restaurant manager on embarkation day. They'll usually be at the Triton's restaurant for a few hours in the afternoon entertaining these types of requests from guests.
I hope this helps! Have a great time planning your onboard activities, Kathleen. Please do let us know if we can help you in any other way.
