I mostly go to Epcot first on arrival day. Note I said first. #1 I have an AP so I go to Epcot and then hop to whatever park I have reservations for the next day to knock out a ride or two. #2 I drive down from Georgia and usually arrive anywhere from noon to 3 so how much time I spend in Epcot depends on what time I arrived, if a festival is happening and how tired I am. I tend to say in Swan/Dolphin about 80% of my trips and always have at least 5 nights so with 4 1/2 days at minimum I can pretty much do what I want to in all the parks. For some reason, I find from Swan I tend to go to HS first and from Dolphin I tend to go to Epcot first. I walk it 80% of the time, I do take the boat to HS if it's later in the day and I'm tired. I never take it to Epcot. If there is no festival happening at Epcot when you go, I don't think in Feb. it would be too crowded for you to need the extra night hours. So really, just toss a coin between Epcot and HS.
