I've been doing spreadsheets for over 20yrs. Mainly to make sure we balanced our time at the different parks, but also to keep track of FP times, dinner reservations, etc.The continued spreadsheet-ification of taking vacation trips for pleasure has been sadly fascinating to me. I remember when you only had to worry about dining reservations...
This change means I don't need to plan out FPs 3 months out, back to the old FP process of same day.
I hope they keep the dining reservation window at 2 months, that is way more sane than 6 months out.
