I wonder when Disney will do the sailaway party, I'm assuming at 9 pm. So all those with late seating would miss it??

It says on the Disney site that we leave port at 9 pm.
We have early seating... Maybe we should do a new roll call and everyone can list who's in their party and whether they have early or late seating for dinner.
I called Disney about what time to board and they said the usual time between noon & 1 pm. We were planning on going to port early then, eat lunch at the buffet. After lunch if we aren't too tired we were gonna walk around the port area there. Otherwise, we weren't planning on touring Barcelona until the last day as our flight doesn't leave until the following day.
In addition to that I'm just not sure how we'll be feeling jetlag wise. So we might play it by ear for the 1st day. I'm coming from the West Coast. We fly out on July 5th at 4 pm arriving in Barcelona on July 6th at 4 pm. Would we be over jetlag by Saturday?
