We were there 1/1 - 1/6 and stayed at the Boardwalk. During that time the IG opened at the same time as the other Epcot gate. The entire park had the same hours, FW and WS. The buses started running 1 hour before park opening. I believe I saw a sign that said that about the Skyliner, but since I did not stay in a Skyliner resort you better not count on this.
