Sources say William wants to spend some special time just with him and Catherine. The couple plan to take their children, George, Charlotte and Louis, in a sign of their commitment to family time. The Welsh family have a history of holidaying on Mustique, including celebrating Prince George's sixth birthday there in 2019. This suggests the island, known for its privacy and exclusivity, has become an important location for the family.

They are expected to stay in a luxury villa, which will feature amenities such as a kids' room with bunk beds, an 18-metre infinity pool and dedicated staff including butlers and housekeepers. These lavish accommodations highlight the need for a relaxing family getaway. Mustique is known for its strict security measures, ensuring the royal family’s vacation remains private and paparazzi-free.

The island’s exclusivity may have influenced their decision to choose this destination. The royal family has close ties to Mustique, with links to the Middleton family and property ownership on the island. This relationship helps explain why they chose the secluded retreat and their familiarity with the area.

The family will participate in a variety of activities during their stay, further cementing their relationship. While little is known about the vow renewal ceremony, the family has participated in a number of activities on previous trips, including a visit to Basil’s Bar, a popular local spot popular with celebrities. The couple place great importance on spending quality time with their children, combining leisure with active engagement.

Furthermore, Prince William’s recent trip to the Kumba immani Millennium Centre in Liverpool underscored the importance of the royal family finding a balance between family life and public duties.
