Our Work: which trips this guide covers

This guide covers how a traveler plans and books an international leisure trip through a travel agent. Here is what it addresses, and what it leaves out.

Five kinds of trip and what each one turns on

We sort the trips in this guide by style and by destination, because a traveler usually has to settle both before anything else. The styles are river cruises, all-inclusive holidays, guided group tours and independent trips built around the traveler's own pace. The destinations we return to most are Ireland and the rest of Europe, Africa and China, since each brings its own paperwork, health advice and calendar.

In a low-water summer a river cruise operator may swap ships, move passengers by coach or cancel a sailing. A CruiseMapper report on record-low Rhine water in August 2026 described one operator cancelling 10 departures and modifying six more, so ask how the operator handles low water before you rely on a date.

Ireland and Europe change most at the edges of a trip. A UK Electronic Travel Authorisation can be needed when an Ireland holiday adds Northern Ireland, England or a UK connection, and the Entry/Exit System has been fully operational at Schengen external borders since 10 April 2026. Each country on a route sets its own rule, so check the route one border at a time.

Africa carries the heaviest health preparation. Proof of yellow fever vaccination or a waiver is often required for U.S. travelers going to endemic areas, and Kenya runs its own visitor permit online. For the current health requirement, the CDC's yellow fever guidance is the place to check.

China's rules are the least settled. A report dated 17 December 2024 said Americans could stay up to 240 hours without a visa only when transiting to a third destination, so confirm the current rule with the Chinese embassy or consulate before you book a China tour.

For all-inclusive and group travel the question is what the price covers. The FTC fees rule bars advertised lodging prices that leave out the total, so a room or resort rate has to include mandatory fees. It reaches lodging and live-event tickets, not cruises or tours, so a cruise or tour price needs its own questions.

This guide gives no prices, no listings and no bookings. We have not taken any of these trips, and the photographs here show what they show, not a visit by us.

Before a trip can be judged, the reader has to know which parts of it the operator controls and which depend on the water, the border or the calendar.

Numbers to confirm before a deposit goes down

Passport book fees and processing times

A first-time adult passport book is listed at $130 for age 16 and up and $100 under 16, plus a $35 acceptance fee at the facility that takes the application. Routine processing is listed at 4 to 6 weeks and expedited processing at 2 to 3 weeks for an extra fee. These figures come from a University of Minnesota Passport Office fee page that reproduces the State Department schedule, so confirm them on travel.state.gov. A Cornell Law School page for the same rule listed lower fees that we could not reconcile with these.

The domestic first leg and TSA identification

REAL ID enforcement at TSA checkpoints began on May 7, 2025. According to TSA's REAL ID guidance, a passport is an accepted form of identification, so a traveler on the domestic first leg of an international trip does not also need a REAL ID.

Card disputes and the clock that starts with the bill

A billing-error dispute on a credit card must reach the card issuer within 60 days of the first bill that shows the error, so the clock starts with the statement, not with the day a problem is noticed. Once the complaint arrives, the issuer must acknowledge it in writing within 30 days and resolve it within 90 days. The FTC's guidance on disputing credit card charges sets out these steps.

Flight cancellations and schedule changes

When an airline cancels a flight and offers no alternative, federal rules entitle the passenger to a full refund of the airfare, including taxes and ancillary fees, on covered flights to or from the U.S. A departure or arrival that moves 3 hours or more on a domestic itinerary, or 6 hours or more on an international one, counts as significant for refund purposes, as set out in 14 CFR 260.2. DOT's refund rules were reported as under reconsideration, so check the current text of 14 CFR 260.6 before relying on it.

Entry permits for Kenya and the UK

Kenya's official eTA site lists a Standard eTA for single entry at $30, a Transit eTA at $20, a One Year Multi-Entry eTA at $300 and a Five Year Multi-Entry eTA at $185, aimed at American nationals. It does not say who is exempt, so read its eligibility page. The UK Electronic Travel Authorisation costs £20 and is not refundable after applying. The Republic of Ireland sets its own entry rules, which this guide has not sourced.

Three health figures that set the timetable

1 dose: For most people, a single dose of yellow fever vaccine gives long-lasting protection. Proof of vaccination or a waiver is often required for U.S. travelers going to endemic areas. Source: CDC yellow fever vaccine guidance.
6 months: Infants 6 months or younger are on CDC's list of people who should not receive the vaccine, so a family with a baby may need a medical waiver instead. Source: CDC yellow fever vaccine guidance.
4 to 6 weeks: How far before leaving CDC advises a visit to a health care provider, because some vaccines need more than one dose. Source: CDC Travelers' Health, travel vaccines.

A health care provider decides for each traveler, not this guide.

Work through the trip in the order its deadlines fall

Start with the passport, because routine processing is listed at 4 to 6 weeks. Next, book the health visit and allow the lead time CDC advises. Settle the card you will pay with before any deposit, since a billing-error dispute must reach the issuer within 60 days of the first bill that shows the error. Last, ask what the operator does if a river cruise or flight changes, because that answer decides whether the booking can still run as planned.
