I already have a cruise booked for 2018, and I am waiting for the RCCL summer 2018 cruises to be released. I have our vacations through 2019 planned or seriously thought out. I haven't booked some things for them, because it just doesn't make sense. However, I have seriously thought about where we want to go, stay, and eat, what we want to do, and when. I like planning though I am bummed that WDW, my son's school, and the airlines don't release their schedules this far out.
