Palo Dinner - difference between First Night and subsequent nights?

Hi there, second-time cruisers here and looking to try Palo for the first time. (Or Enchante but it’s all booked!)

I was able to grab reservations for Palo First Night or on day 2. I was curious if the first night is actually different than the rest of the nights? Also because it will let you book First Night + another night, but not two of the subsequent nights. This makes me think maybe the experience is different.
