I'm sure there will be more notes coming, but in general - dining is 60 days out. Since you are staying at a Disney resort, you can make dining reservations 60 day plus the entire length of your stay - could be a big advantage. You can make park reservations as soon as you have park tickets for your party. Remember - no park reservation, no park entry. If you are planning on park hopping tickets, you still need to enter the original park you reserved for that day, then you can hop after 2PM later in the day. As for ride reservations, you can only purchase
Genie+ and/or the Individual
Lightning Lane attractions day-off. At 7AM, you'll be able to purchase up to 2 ILLs. If you also decide to purchase Genie+ for the day (you do not need to purchase Genie+ in order to purchase ILLs), you can make your first Genie+ reservation at 7AM. You'll want to read-up on the ins and outs of Genie+! You can use Genie+ throughout the day, as long as you have a smart phone and the
MDE app to do it. You'll also want to actually purchase Genie+ prior to 7AM so you can use it most effectively.
If you have the new Guardians of the Galaxy attraction on your list of must-dos, that particular attraction has a Virtual Queue option available for free, but you need to grab a spot in line at 7AM - you'll get a time to return later in the day. Hope that helps a little bit...... I can confirm your statement - things have most definitely changed in the past few year! Hope you have a fun and memorable trip!
