I just confirmed a cabana #20 for our May cruise. Question?? Is lunch served at Serenity Bay or do we have to go back o Cookies? If it is served there is the food different than what is served at Cookies? Cabana location? Is there a map that shows the where #20 is? Thanks in advance! This was a hard decision to make, spending a fare amount of money on the Cabana is something that we have only talked about!
