I've done it alone. Get to Epcot for opening. Get coffee and breakfast from the Fountainview cafe and sit outside and watch the fountain and all the people skittering past not noticing it. Browse Mousegear for an hour. Take in Living with the Land. Slowly drift through the rose garden and get to World Showcase for opening. Slowly drift around taking in the entertainment. Stop in Germany for a Becks. Snack around the world. Linger in France at the patisserie. Just drift and watch people and things. Head out around 7pm and hit Downtown Disney for a couple of hours - sit outside Ghiradelli's with an ice cream before heading back to the hotel.
