You should be able to request the cars suite when you book, it gives you the option to pick between the themes if they’re available. We stayed in a Nemo suite for two nights st the end of our last trip (at ASMu suite)because my kids were dying to check out the resort. I think the memo suites are preferred suites, so they cost more.We also always stay DVC so it was s change for us. Loved the pool and all the theming. The cars section is amazingly themed, many great opportunities for pictures. We really liked AoA, the food court was great, theming was great, rooms were cute but not as big as DVC 2 bedrooms were used to. And they don’t have a complete kitchen. It’s also nice being close to Pop, you can walk around that resort and check out the theming there too. Have fun! Edited to add: I just noticed that you already booked. I’d call and request cars if it’s available they should be able to accommodate you.
