Is there anything or anywhere you usually go on your first day?
For us we arrive in the evening so we tend to go shopping for groceries and then sometimes, go for a walk around DTD depending on how tired we are.
Our first full day is normally a wander around World Showcase, we get there for around 11am and make straight for France to the Boulangerie Patisserie. After that we go back to sit by the pool in the sun :D
What do you like to do?
