For the ticket piece I don't think you will find a better price. However, it is possible that something like free dining will come out and that could make the total price better... I find getting a discount on the room and tickets better for us, we haven't used the dining plan on any of our trips. I'd do the math with "rack rates" and see. There are often room discounts that come out you could apply later, but the ticket deal is only on until sometime in February. I doubt you will see something better come out before it's over.
I intend to buy some tickets, I'm just trying to figure out for how many days and if we can actually plan a trip before they expire. I have two cruises coming up that are eating all my travel budget. I'd like to go in August because we get the best price on the room and kiddo doesn't miss any school. But... perhaps a November-ish trip would be nice so we can do the Christmas party. Or late October for Halloween (we went to two of the parties this past August and really enjoyed it). Any way
