An Hour Round the Palace, with an Emirati Guide. One hour, and the only way to see the parts of this building nobody sleeps in. The route takes the main dome — gold, mother-of-pearl and crystal, and worth standing under for a while — then one of the Palace Suites, then either the Etihad Ballroom, which seats 2,400, or the auditorium, which seats 1,100. It ends with a Palace cappuccino, a Palace cake or a Palace hot chocolate, all 3 of which arrive with the building stencilled on them. Book it through the concierge; it does not run on demand.
The Marina, and What Ties Up in It. A working superyacht marina on the property, with a berth-holders' lounge and terrace, a meeting room for 10, laundry, a florist, club-car transfers and a helipad for owners who would rather meet their boat than drive to it. Guests who are not arriving by sea get the other half of it: a 3-hour island run by boat with a captain, two menus to choose between, towels and a sun marquee, up to 6 aboard; or a charter through the marina's Swiss Yachts partnership. It is paid for in full to hold the date and refunded in full up to an hour before.
8,000 Trees, and the Bees in Them. The gardens run to 85 hectares and about 8,000 planted trees, which in this climate is infrastructure rather than landscaping — and the count of migrating birds turning up in them goes up every year. Out among them are the hives, and somebody will walk you round: how the colony works, what it forages on here, and the honey that comes off it and goes onto the breakfast table at Vendôme. It takes 20 minutes rather than an afternoon, and it is the one thing here a child remembers a year later.
A Day Here Without a Room. Day passes are sold here, which is unusual and useful if you are in Abu Dhabi and staying elsewhere. The Mandarin Pass is beach and pool. The Palace Pass turns the whole amount into credit against food, the spa and Kids Palace, adds an hour of padel, and covers 2 children under 12. The Palace Luxe Pass adds a room for the day, 10 until 6 — a Deluxe Room or a Sea View Suite. All of it is booked ahead, none of it is walk-up, and the concierge will price it against your date.
