We have 2 parks days that are redeemable from 6th January through 9th January.
We plan to do parks on 7th & 8th. One park each day and are staying off-site.
If we plan to do parks on the 7th and 8th, can I still book on the 3rd of January (3 days prior to when our tickets are redeemable) for 7th and 8th or should I book on the 4th?
If we decide to change parks for the day, are we able to change the already booked lanes or all paid passes price would be lost?
Heigh Ho Ho Ho! The good news is, according to the Disney website, you can purchase Multi-pass and start booking three days before the FIRST day of your date based ticket. Good luck on the 3rd! Let us know how it goes!
I don't know the answer to question 1, hopefully someone with more knowledge of it can answer. Usually the wording is 3 days prior to the start of your trip, which technically for you is 6th Jan.
For question 2, yes you can change your lightning lanes to a different park (or even a different day if you needed). Obviously when you do this, any existing lightning lanes you'd booked would be lost but then of course you would just book new ones.
