I should probably elaborate, in addition to using FP, we also followed all the advice we received from DISers; hitting "slow-loaders right away, going to parks the day after their EE day, etc...
And, it has been over 20 years since I've been to WDW any other time of year, so I don't have anything to compare it to. We may have been in the right place at the right time, but we've been very happy about crowds during "Joizy Week"!
