FYI, the youth counselors no longer "collect" kids during dinner, just FYI. That was gone during covid and never came back.
OP, if you don't get an email in the weeks leading up to your trip, you didn't get moved to main dining. You'll need to go get in line to ask for it first thing when you get on board. We have been moved to main dining every time except for once. At the advice of others on this board we tried out late dining (first time in 7 cruises) and while it didn't ruin our trip, it was NOT for our family - we are east coast with 3 kids. 2/3 of which slept through dinner at the table, very cranky. It was not comfortable and while our dining team tried to make it enjoyable, our kids were miserable which means we were miserable. I left around the 1st course every night to take the little kids to bed before we became "those people". We also typically do longer cruises though. Since you are doing the Wish, the trip is going to go by like a blink. Just saying, if you don't get moved for some reason, it won't be the end of the world since the trip is so short. That doesn't really sound like a silver lining but it could be.
Also, if you do main dining, you still get a late show. My kids have never had trouble sitting through the late show. The shows are shorter than dinner, so they are always in bed earlier than they would have been if we had late dining.
