When I'm looking at planning a future trip and Disney hasnt released packages and info regarding increases in price, I can still do quite a lot of planning. Historically Disneys price increases have been raised yearly, so I'm thinking ballpark figures of anywhere around 10 - 20%, so I use that as my starting point. Then I set my budget and savings goals to work harder about putting more money aside. You can still plan ahead on paper, before reserving... your dining spots, FP+ desires, tours and extras. Money saved that ends up not being needed when prices are released, or Disney offers a discount, either get put away for something in the future or put back into doing something at Disney that I wasnt counting on affording to do. our trip for May was cancelled so I know what my quote was for that stay, now I'm conservatively adding 20% to those figures for planning our 2021.
