HOTHS eat a Palo on Halloween Night?

[annabelle004]

We are going on the 7 night W Carib in October. I have Palo dinner booked already, but for scheduling reasons the night I really want is the same night as the Halloween party. At first my thought was to put Palo on a different night because we would want to do the party as a family. But in reality, my kiddos are 13 And 15 and (assuming they like kids club activities) will likely prefer to do teen parties.
So - Is there a good way to experience a little of the Halloween fun as a family and still fit in Palo?
