Hi JasonG, Welcome to Cruise-Chat!
My wife and I will be on the Freedom Oct. 15th too. This cruise will be a Crown & Anchor Membership cruise. Of course you don't have to be a member, but there are a lot of special parties for members. Maybe we can meet sometime during the cruise. This will be our 30th cruise with RCCL.
You will be able to wear shorts for breakfast and lunch in the main dinning room and in the Windjammer. Shorts are not allowed for dinner in the main dinning room, Chops, and Portofino's.
