I admire the restraint of waiting until 60 days. I start checking out mine as soon as I've booked the cruise; go the TA to book it and then set it up as soon as I get home. I also check my
DCL/WDW and Touring Plans account regularly just to check out the number of days until I go in case somehow one of them has miscalculated and the trip is coming sooner than anticipated (I wish).
