if one of your segment are families,
I have a really unique and cute idea for branding, promoting and long-term marketing for you.
A children's book (age 2 – 6) about staying in a hotel or flying aboard while on vacation.
You can put your logo on the cover of the book, and on every page.
It can be in any language.
If you give some giveaways for your families customers, you can add or switch for this children's books.
