Reading on holiday produces some of the most-rated travel experiences in retrospective surveys. The combination of sustained leisure time and undivided attention produces reading experiences home life doesn't permit. Plan reading material with the same deliberateness as accommodation.
What to plan
Different books from home reading (try genres you don't normally read). Long-awaited novels you haven't had time for. Kindle for travel weight. Backup books in case one disappoints.
Where it matters most
Beach trips. Long flights. Rest days. Evening downtime. Most travellers have more reading time on holiday than at home for months.
Pack 2-3 books per week of trip (Kindle for long trips). Many adults' best reading experiences happen on holiday because the conditions are uniquely supportive.
