No, the poster we are talking about asked, not stated: Can you reserve a large table for Anytime Dining for just a single night?
If you are going to answer another poster issue don't quote me, quote them.
And, the post is true. MTD booking system is set up to allow for booking only one night if you want to - that is what the poster asked and what was posted.
Welcome to CC.
That's because she doesn't know, no one does. The price of the package (as is almost everything in the planner) is dynamic - it could go up/down between when you book and when you go into the planner a few minutes later to book something.
Cruiseplum is great for doing this type of high level comparison:

Early traditional may be full by this time but you might be able to get on a waitlist. Otherwise, go to the MDR as soon as you board and talk to the host about changing - might be tough with a big party. Book something in MTD just so you have a booking.
