Four lines on a rate card cause most of the confusion, because they are presented differently by different operators. Know what each means and a card stops hiding its true cost.
Service charge: in or on top
The service charge is the operator’s management and concierge fee, 8 to 12 percent on the Mediterranean and 15 to 18 percent in the Caribbean. Some cards fold it into the headline rate and some show it as a separate line, which makes two villas look mispriced against each other when they are not. Always ask whether the quoted figure already includes the service charge before you compare.
Tax: a percentage of a moving base
Government and local taxes run from 6 percent in Portugal to over 20 percent in parts of France, and they apply to a base that often includes the service charge. So the tax line rises over peak even though the rate stays the same, because the base it is calculated on is larger. Read the tax as a percentage of the all-in, not of the headline.
Included versus excluded staff
Every card names which staff sit in the rate and which are extra. A housekeeper and a caretaker are usually included, the chef and a driver usually are not. The trap is the in-house chef pushed as the convenient option, who is sometimes a worse cook than an independent for the same money. Check the inclusions list, because it changes the all-in more than the rate does.
Deposit and cancellation: cash flow and risk
The security deposit, $5,000 to $25,000, is refundable and so is cash flow, not cost, unless the operator offers a non-refundable damage waiver of 1 to 3 percent instead. The cancellation line is the real risk: most operators take 30 to 50 percent on booking and the balance 60 to 90 days out, and that balance rarely comes back. That single line is why travel insurance earns its small premium.
