Savi's is not very difficult to get. I couldn't get Oga's or Homecomin or a late Beaches and Cream but got Savi's easily. I am only staying on site one night so only got 60 days+1. Just to give you a heads up for prioritizing reservations. I am using two reservation finders online so I hope I can get Oga's for one of the days I am in Hollywood Studios.
