Planning a holiday for three generations is a logistics problem dressed up as a treat. Somebody has to hold the dates, the budget, the cabins, the dietary requirements, the flights from two or three different cities, and the fact that one grandparent does not do stairs. A cruise removes a surprising amount of that burden, but only if the planning happens in the right order.

1. Who is actually coming

Write the list before you look at a single ship. Names, ages, which city each household flies from, and anything that affects a cabin: a toddler who still naps, a teenager who needs their own space, a parent who uses a stick. The list decides the ship. Skipping this step is how families end up on a beautiful ship with no children's programme and a cabin two decks from Grandma.

2. Who is paying for what

Often a grandparent is paying for the cruise and the adult children are covering flights or excursions. Decide this early and tell us, because it changes how we build the proposal. Ships that include excursions, drinks and gratuities make a shared bill far simpler. Ships that charge for everything separately give you flexibility but need a conversation about who signs for what.

3. The dates, honestly

School holidays constrain most families to a handful of weeks. Those weeks are also when the best family suites sell first, on every line. If you must travel in late July or August, plan nine to twelve months ahead. If any household can shift by a week into early July or September, say so. The saving in price and crowds is usually significant, and the weather in the Mediterranean is at its best.

4. Cabins before anything else

Connecting suites are the scarce resource. On most luxury ships only a handful of pairs exist, and they are rarely visible on a public booking site. We ask the line directly, hold what suits the party, and then arrange everything else around it. Midship cabins are steadier for anyone who worries about motion; a deck close to the pool suits young children; grandparents often prefer to be near the lifts and the main restaurant.

5. The days ashore

A single excursion rarely suits a seven-year-old and a seventy-five-year-old. We plan two tracks for most port days: something gentle and something energetic, meeting for lunch. Private guides and vehicles make this easy and usually cost less per person than you expect for a party of eight.

6. Before and after

Fly in a day early. A night in a good hotel near the port turns a stressful embarkation into a lazy morning, and it is the single best insurance against a delayed flight. At the other end, a night or two in the disembarkation city lets the family end on a high rather than in an airport queue.

What the specialist does

All of the above, in one place, with one person to call. We shortlist the ships, hold the cabins, book the flights so everyone arrives on the same afternoon, arrange the hotels and transfers, and plan the excursions around the ages in the party. Nothing is confirmed until you are happy with the plan.
