What does an all-inclusive holiday usually exclude?
"All inclusive" is a marketing term, not a defined standard. What it covers varies enormously between operators and even between properties in the same chain, and the exclusions are where the cost creeps back.
Commonly included: accommodation, buffet meals in the main restaurants, local-brand alcoholic and soft drinks, and some non-motorised activities.
Commonly excluded, and worth checking each time:
Premium and à la carte restaurants. Many resorts include only the buffet, charging a supplement for their speciality restaurants or limiting you to a set number of visits per stay.
Branded and imported drinks. "Local brands" can mean the house spirit only. Imported spirits, wine by the bottle, cocktails and speciality coffee are frequently extra.
Motorised watersports and excursions, almost always.
Spa treatments, and sometimes even the sauna or thermal area.
Airport transfers, unless explicitly part of a package.
Resort or tourism taxes, which in some destinations are collected locally in cash on arrival and cannot be prepaid.
Tips, in regions where tipping is customary.
Wi-Fi, though this is increasingly included.
Minibar restocking, safe hire and beach towel deposits.
Timing catches people out too: all-inclusive normally starts at check-in and ends at check-out, so a late flight can mean paying for a final lunch.
Some operators distinguish "all inclusive" from "ultra" or "premium all inclusive", with the latter covering branded drinks and à la carte dining.
The reliable move is to read the specific property's inclusions list rather than the brochure headline, and to budget for excursions separately.
One structural point worth weighing: all-inclusive is priced on the assumption that most guests eat and drink on site. If you intend to explore local restaurants, you are paying twice for the same meals — a room-only or half-board rate often works out cheaper for that style of trip.
