Hi! I'll be there that same week. Last year, we arrived the day before Memorial Day and spent Memorial Day in Epcot. Not bad at all! Our resort was pretty busy (surprising for OKW), but the parks weren't too bad. Remember that there's a DVC event 5/25-5/27. You might want to avoid Epcot on 5/25 and MK on 5/26-those are the days for after-hours DVC events, so it might be busy during the day. Wear your lime green!
