I see the posts for opening day prices, but I can't find anywhere the schedule of opening days. I am looking for November and December 2021 for our first ever cruise and wondering when the opening day for bookings for those will be. Also, is there a post that shows info about moving and cancelling reservations? I'd like to lock in pricing the day it opens, but I can't even book time off for that fall until the March before so would like to learn about moving cruise bookings and cancelling if needed. I see the info on DCL's page but know I've read lots of snippets of good info on that early booking process somewhere here before over the years. I see that awesome post with all the info at the top but couldn't find these specifics. TIA!
