Airfare is the largest variable. Off-season flights to Rome or Lisbon cost a fraction of summer fares, and a land-only booking lets a pilgrim use miles or a cheaper routing. The existing page on land-only versus air-inclusive pilgrimages explains that choice.
Three-star hotels near the shrine are standard on parish pilgrimages; four-star hotels in central Rome or Jerusalem raise the price noticeably. Group size works the other way: a large group spreads the cost of the coach, the guide, and the priest across more people, while a small private group pays more per person for the same services. The existing page on small versus large groups weighs that trade.
The single supplement is the charge for a room alone, and it can add a meaningful share to the base price; the existing page on single supplements explains how to avoid it by accepting a roommate. Rome hotel rates rise around Easter and canonizations, and the shrine of Fátima notes that its May and October anniversary pilgrimages fill the town. Extensions are priced separately.
What is usually included: hotels, breakfast and most dinners, the coach, a guide, church entrance fees where any apply, and the services of a spiritual director. What is usually excluded: lunches, tips, travel insurance, optional excursions, and drinks. The existing guide on pilgrimage costs and what to budget for lists line items. To compare companies, ask for a list of inclusions and exclusions in writing and compare the number of nights, the hotel names, and the walking days, not only the headline number.
