On a Disney vacation:
Be a morning person. At home, I am super grumpy until about 10am. At Disney, I am up with the birds and cheerful.
Walk a million miles a day.
Become adventurous. I will try news foods, drink alcohol during the daytime, ride thrill rides, and generally try things I normally wouldn't in real life.
Non-Disney vacation:
Do touristy things like carriage rides, visit attractions, or shop at touristy shops for silly souvenirs.
Visit museums, tour historic sites- generally do more cultural stuff than I do at home.
Walk around the area and notice architecture.
Spend no time watching TV, looking at my cellphone, or surfing the web.
