What PI is for. PI on the tour operator policies we arrange can respond to civil liability arising from your professional services, such as the planning and booking work described on your schedule. On a literary tour that means the itinerary, the timed entries, the bookings with bookshops and venues, and the advice you give about pace and suitability. If an error there costs a client money, PI can respond to the client's other losses, subject to the wording, the schedule and the underwriter's assessment. It doesn't refund the tour price, and it doesn't cover a quote or cost estimate that turns out too low.
Claims made means keep it continuous. PI on the tour operator policies we arrange is typically claims made and notified: the claim has to be made and reported in the same policy period. If the retroactive date is set at the start of your policy, errors on tours before that date aren't covered. If you change insurers, keep continuity so a complaint about last season's tour still has somewhere to go. On at least one wording we place, several claims from one itinerary error can be treated as a single claim, with one limit and one excess.
Talks, readings and the people who give them. A guest author, a local historian or a bookseller giving a talk is a contractor unless you employ them. Tour operator policies we arrange can respond to your liability for what a contractor does, but don't insure the contractor, and at least one wording we place requires you to check they hold their own liability cover. Put the speaker's fee, cancellation terms and any content limits in writing, because a cancelled talk isn't insured, and what a speaker says on your program is part of what you sold.
When the program itself fails. The clearest Australian authority is not a literary tour. In Moore v Scenic Tours Pty Ltd [2020] HCA 17, a European river cruise tour booked in 2012 was severely disrupted by flooding. The High Court held that damages for disappointment and distress were available under the Australian Consumer Law, and restored an award to the lead passenger of $10,990 for the lost value of the tour plus $2,000 for disappointment and distress. A literary tour is sold on promised content in the same way: named houses, named speakers, a set route. On the tour operator policies we arrange, PI doesn't refund the tour price and cancellation is generally excluded, so don't assume a claim like that is insured, and ask the underwriter how it would be treated. Our overseas tours guide covers what to put in place.
Selling into the UK. Whether the UK's Package Travel and Linked Travel Arrangements Regulations 2018 reach you is a question for a lawyer. The parts we read apply to packages sold or offered for sale in the UK, where the organiser is liable for the performance of every travel service in the package, whoever delivers it. Their insolvency protection rules also reach an organiser outside the UK that directs its sales to the UK. If a UK retailer sells your package, the regulations put the organiser's obligations on that retailer unless it can show you comply, so a UK retailer may want matching terms in its contract with you.
