We always hop! Love to do early and late EMH so we usually hit two parks a day! If MK has late EMH with the park open till 2 am like 2 weeks ago, we hit another park in the morning, then head back to MK around 8 or 9pm when it's cool and quieter! Sometimes we hop just for dinner, I think it depends a lot on how frequently you go to Disney, we like resort time tool, swimming etc., its refreshing! Some parks are 1/2 day parks for us, DHS & AK, so we go elsewhere earlier or later depending again on EMH!
