The US actress will exchange vows with Britain's Prince Harry in St. George's Chapel in London at midday tomorrow, and she's making sure she'll get a good night's sleep by staying at the beautiful Cliveden House on the border of Berkshire, where she'll be doing some last minute preparations with the aid of her mother Doria.
The charming Cliveden House was once the home of Prince Frederick of Wales and is a half hour drive away from Windsor.
It was revealed as the hotel in which the bride would reside the night before her big day in a statement by Kensington Palace earlier this month, while the groom will stay at the luxurious Coworth Park, home of the Guards Polo Acadamy.
Cliveden House features an outdoor pool - the last remaining listed outdoor pool in England - and a spa, where Meghan could enjoy some pre-wedding pampering with her mother.
Rooms at the Italianate mansion go for around €600 per night during the summer months while suites can fetch over €17000.
Earlier this week, Chelsea footballer Cesc Fabregas gave royal watchers a sneak peek of the venue when he and now-wife Daniella Semaan tied the knot there in front of close family and friends.
The couple shared several photos of their all-white ceremony at the beautiful venue, and some of the reception inside the gilded walls of the glamorous house.
Cliveden House has been a firm favourite of luxury-seeking guests for years, and could be the perfect spot for Meghan to enjoy a pre-wedding run on the grounds of the 376 acre sprawling estate.
Past guests include George Bernard Shaw, Charlie Chaplin, Winston Churchill and Noel Coward among others.
