According to the Telegraph newspaper, more than 2 million people are planning holidays around the event, which is slated for April 29. Of course, the big day is an official holiday, and it just so happens to be sandwiched between the Easter holidays (April 22 and 25) and May Day (May 2), which means there will be just a short three-day work week splitting up two long weekends.
The result: There's a rare opportunity to escape on a spring cruise without having to take too many days off work. Thankfully, there's still time to capitalize on this unique occasion.
