That would be 2018? How long are you staying? Sun May 13 is Mother's day, do you want to be at WDW then? April 29 will end up a few more points as 2 days are in magic season. The crowds will be heavier on May 4 and 5, Star Wars and Cinco de Mayo.
We are staying offsite the Friday and Saturday before, so 7 nights total, but we only have enough points for 5 nights DVC (our first resale contract and it wasn't loaded). So we would be checking out either Friday the 4th or the 11th.
