If there is an attraction, museum, or other site you really want to visit…do you book your tickets ahead of time?
Many places allow you to book on their website in advance. You won’t have to stand in line if you can download your tickets at home. Just don’t forget to take them with you.
Or, if you can’t print them at home…you can pick them up at their will call office. This also allows you to skip the long lines.
The same goes for a restaurant where you really want to eat. Book it advance. Just keep the reminder on your phone or with you.
