not for the EPCOT resort guests
aside from valet, another option is the non-resort guest lot across the road from the BW (free, behind the hess station). you would need to walk from your spot, cross the road, up to and thru the BW lobby, keep walking along the BW and over to IG - a bit of a hike.
another option is to go to DHS, and ferry/walk to IG.
all are options if you just want to use IG, but all require time and/or money (valet, parking at DHS if offsite) - none are cost/time effective if just trying to avoid the EPCOT parking fee tho.
