IMO you'll still find a lot of people do not get up that early, even for EMH. Especially if it's a 7 am EMH. Now whether it's worth it or not depends on what park and your plans for the day. MK - I'd say worth it b/c you can always find an open ride to get on. HS - I can't voice an opinion on fact since I haven't been their since TSL opened, but I'm assuming it would still be a little tight with limited attractions (by total number) and everyone wanting to do TSL. We've typically hit up EMH, did as much as possible, then when the park got too packed, bounced over to another park.
