On Jewel out of Boston this fall on 7 day and wanted to know (my TA doesn't and can't get a response from RCCL except standard reply) how many formal nites 'cause there is only 1 day at sea and that is usually when they are held? On port days everyone returns around dinnertime. Is there a semi (or informal) nite too & when wld they take place? Hope someone knows and can enlighten me. Many thanks in advance. Happy cruisin'!
