Having done IASW in that first hour after EMM before, I don't recommend it. It takes too long and just eats valuable minutes! My personal recommendation would be to at least get in one E-ticket ride (a big, popular ride) right away. Something like Space, BTMR, Splash. Of your options, I'd probably do Space, Astro, restroom to get sick, Speedway if you have time, then breakfast. Good luck!
