Just ask! On the last 7 day cruise we did 3 Polo's and a Brunch. I know they don't like to give you more then one reservation - you can tell by the look they give you. But - ask anyway!!!
You can go to Palo every meal they have an open slot, but may only be allowed to reserve the additional slots a day in advance. Once on board talk to the Palo staff and ask.
As advised, talk to Palo staff. We've had friends who actually went to Palo every night for dinner instead of the dining room (outside of our budget LOL). And we've known people who did more than one brunch. If they have openings, they want to fill them!
