The ticket page lists full access to the palace zones, including the Great Hall, Presidential Gifts and the Qasr Al Watan Library, entry to the Palace in Motion show, free Wi-Fi, a free shuttle bus and parking, and one-time use only. The FAQ describes the general admission ticket as access to the Qasr Al Watan Tour, the gardens, the Visitor Centre and all zones, exhibitions and public spaces.
On Wi-Fi the palace contradicts itself. The ticket page and the booking channel list free Wi-Fi, while the visitor information and the FAQ say there is no Wi-Fi throughout the palace grounds. Do not plan around it.
On the show, the palace's pages agree. The Palace in Motion page says to buy a general admission ticket to explore the palace as well as enjoy the show, and that its own ticket is for the show only, and the ticket page lists entry to the show. So the booking channel's separate ticket, at AED 25 for an adult and AED 12 for a junior, is the show alone. Our own listing says the show may require its own admission, which the palace's pages do not say.
The shuttle needs the same care. The visitor information says a free shuttle runs between the Visitor Centre and the palace entrance, and the FAQ says the palace provides no transport to or from it. Read together, that suggests an on-site shuttle only, which is our reading, not the palace's wording.
