So we will be driving to Orlando and our first night will be staying off property, just a place to crash after a 9-10 hour drive. The plan is to hit the parks first thing the next morning with a mid day break to check into the room at some point. Our first day was going to be at EPCOT because we have a Lunch ADR at Akershus (which I am actively trying to push back to dinner if I can). However last night I was watching some ride videos of Slinky Dog with my daughters and they both said "that is the first thing I want to ride when we get there". Looking at the calendar HS does have EMH that morning. My question is if we haven't "checked in" yet would we be eligible to go in for EMH? I know there is online check in but can it be done that early?
