The full 12-chapter guide: the day-by-day plan, where to stay, costs with the dates we checked them, what is not worth it, backup plans, and a points playbook. You read it online in your PerkJolt library.

Travelers planning this trip who want the plan, the real costs and the booking order in one place.

Does it cover points and miles?

Yes. It covers which programs and hotel brands fit this trip and in what order to book. It does not quote card offers.

Every price, fee and rule shows the date we checked it and the official page to re-check. Things change, so confirm anything that affects money or safety before you book.

Can I get every guide instead?

Yes. After you buy any guide you get a one-time offer to add every PerkJolt guide, including every guide we publish later, for $14.99.
