We did it in October and loved it as well. We added it on to our Sept Wonder cruise. As far as your dining rotation, you can "request" a particular rotation, although it is not guaranteed. From all I have read here, most do get it, however!
The price is $349, includes dinner at Palo (the added surcharge is included), couples massage (onboard, choice of aromatherapy or the spa taster), a champagne basket (ours had champagne, a picture album and chocolate), a romantic turn down (kinda cheesy, but still a nice touch

), and champagne breakfast in bed (room service from a special breakfast menu) on the morning of your choice....just not the last day. You can also, as a courtesy, book your Palo brunch, tea and request your dining rotation when you book your Palo dinner and massages, although the added surcharges are not included.
Lastly, we added our REAS on to both cruises well after we booked the cruise. Just get your ressie requests in as early as they'll take them!
