The sleeves contained hundreds of prizes, including stays at the London hotel and hundreds of thousands of Virgin points, which can be redeemed online against hotel stays or Virgin Experiences.
The newly completed hotel features a rooftop restaurant, a private gym, treatment rooms and a rooftop bar. Guests can also find a hi-fi bar, Hidden Groves, inspired by Japanese listening lounges.
Branson added: “It’s a tribute to Virgin’s music roots. We built our name on records – now inside our beautiful new hotel, we’ve built a space where people can enjoy them again. Who doesn’t remember visiting a Virgin Megastore and listening to music before choosing which album to buy? This is exactly what I wanted to recreate with Hidden Grooves.”
