Don’t feel like you need to park hop every day of your trip. The option is nice to have, and something I use all the time, but not ever day of every trip. Use it as needed. The cost of the upgrade is worth it if your touring calls for it.
To answer your other question, I would probably just go to Epcot at rope drop, but I do rope drop every day. MK EMH wouldn’t be bad if you don’t want to arrive to Epcot until 11. I would totally do it, but your mileage may vary.
