The above reply is correct. You are still limited to how many active reservations the key allows, but the resort bucket so far has remained *extremely* robust with its availability. There was one Saturday in October that showed DCA starting only, but everything else was wide open when all other buckets had a lot of either single starting park days or flat out “sold out” days, even the single day ticket bucket.
My belief is that they are really trying to always have the resort bucket be an option, even for next day reservations or a few days away. I’ll have used my first two reservations on Saturday the 16th and Sunday the 17th and just need two reservations (above my 6 limit) for Saturday the 23rd and Sunday the 24th. So far observing that bucket, making a new one from it on the 16th for a day seven days later shouldn’t be a problem at all…
