I know this question has been asked in so many ways, but here is my bottom line question. We arrive in Orlando Saturday evening, March 4th. There is no way my kids will wait until Tuesday to go to MK. We are staying off site, so we can't take advantage of EMH. So...would you go to MK on Sunday when they are having evening EMHs or go on Monday...the rumored busiest day of the week? We have not decided yet if we are getting park hopper passes...our kids are 8 and 4 and we're not sure if they will have the stamina to make use of much hopping! Would love suggestions from seasoned veterans!
