I agree it totally depends on what you want. We thought we wanted to be in Lion King due to the theming, it being a bit quieter and being between both the busier and quieter pools, but we got put in Nemo and it was SO hot (we’ve gone three Augusts in a row and one year was SO much hotter and sunnier than the rest) that we were so grateful to be close to the pool, skyliner, and drink refills. We’d love to try Lion King next time though! Honestly they’re all great, if you have young kids I’d lean towards whatever theming is most appealing.
