As of my last knowledge update in January 2022, I don’t have information on Bukayo Saka sharing exclusive photos of a luxury vacation on a yacht worth more than 23.3 million pounds. My training data includes information up to that date, and I don’t have real-time updates on specific events or social media posts.

It’s important to note that information regarding celebrities’ activities, including vacations and social media posts, can change over time. If this event occurred after my last update, I recommend checking recent news sources or Bukayo Saka’s official social media accounts for the latest and most accurate information on his activities and posts.
