We had second seating when we booked, were on the waiting list for main dining, and thankfully were switched over to main dining about 6 weeks out from our cruise. I had prepared for second seating, however. The plan was to feed the kids snacks either in Cabanas or room service, then take them with us to the second seating. You can let your waiter know that you want to participate in the Dine and Play. They will bring your courses as usual, but will expedite the kids' meals, and after about 45 minutes castmembers from the kids' clubs will come to the dining room to escort the Dine and Play children to the kids club. They get to play, you get to enjoy the rest of the dinner. You may not want to do it every night, but it seems like a great option if you are stuck with second seating. Good luck!
