If you are going before 4/20, I have heard that within 10-15 minutes of rope drop the line grows to 5 hours in Epcot. So you probably want to get to Epcot pretty early so you are at the beginning of the entrance line, or wait until later in the afternoon. People are literally running to the m&g area when they get inside the park, so keep that in mind, too. I've also heard they cut the line some days if it's too long by like 4:00 or so, so probably try mid-afternoon to see how long it is.
I will be there Sunday and have an 8:10 Akershus ADR. I can let you know what happens after Sunday.
