A family of five hits the same wall in every city: the rooms that fit you are scarce, and the days out are priced for two. Splitting a week across two cities does not fix that, but it does mean two shorter accommodation searches instead of one long one — and, on this pairing, an hour and a quarter in the air, and no time-zone change.
Each half links to its own full plan, where every pick can be swapped for a ranked alternate and the whole thing re-prices for your party. Why party size changes which tours to pick.
