If you want a basket, why not contact Shirley and see if you can mail her a check before the cruise. That way she could do a wonderful basket. I know we used our credit card to order a wonderful basket with Shirley, but she's so sweet, she may be willing to work with you if she can get payment before your cruise. It doesn't hurt to call her and ask. My DH absolutely loved his beer basket that she put together. Not really on the "romantic" side, but definately something he loved!
You could also bring your own bottle of champagne tucked in your carry on......just be prepared for him to ask why your bag is so heavy.
As for Palo - yes the definatley have tables for 2. And I would highly recommend going no matter what. Even brunch can be romantic...a quiet aftenoon eating luxurious food while sailing across the blue ocean...ahhhhh!!!!
