METD

We are celebrating our anniversary on Alaskan cruise with my son and daughters families. There will be 11 of us - adults and college age except for a 10 and 12 year old.  We really want to dine in the MDR at dinner as a family but the largest table they show we can sign up for is 10 people. Do you know if they can make an exception to add another chair, esp since one is a 10 year old?? Only other option is to signup for 2 tables of 6 but am afraid they will be separated in the room... Calling Princess is no help as they say check once I get on board - probably too late by then . Any thoughts??

We are taking our first Transatlantic cruise on Celebrity in late October from Spain to Ft. Lauderdale, FL. What weather temperatures should we expect while on the water as we would like to be outside as much as possible? How rough do the seas typically get? Really looking forward to the trip.
