we are usually a group of 20 and our TA goes first thing when on ship to set up our tables. sometimes we get one long table or sometimes they can only give us 2-4 tables next to each other and we just switch our seats every night to visit with everyone. But make sure you set it up ahead of time first thing and get the name of the staff member who did it - sometimes the dinner time staff doesn't know you took care of in advance and give you a hard time !
