Prince Harry and Meghan Markle have somehow been able to keep their relationship intensely private over the last few months, including their recent vacation together to Africa.

Though few details of their three-week getaway have emerged, it’s been reported that the would-be royal pair spent time in Botswana to celebrate Markle’s 36th birthday. Next, the couple reportedly traveled to Zambia, where they stayed in an upscale safari lodge that has not been identified.

“It was a very, very private visit,” a source told People. “They stayed at a beautiful lodge in Livingstone.”

While no one has confirmed exactly where the couple stayed, we would bet on a place like the Royal Livingstone, a 173-room hotel featuring wildlife sketches and views of the Zambezi river and the Acacia forest. The do-good celebs might enjoy this hotel, as it allows guests to take part in socially responsible initiatives, such as helping local women tie-dye textiles.

Finally, rumor has it that the duo took a helicopter ride to visit one of Harry’s favorite locations: Victoria Falls.

The breathtaking falls, which are named as one of the seven natural wonders of the world, would make the perfect backdrop for a royal engagement.

Rumors have swirled that Markle would come back from this trip with a shiny new bauble on her left ring finger, (just like Kate Middleton did on her vacation to Kenya with Prince William in 2010). However, as Vogue noted, others believe a royal engagement won’t be announced until December to avoid competing with other royal events this fall.

“December they can announce the engagement and they'd be free to marry next year; I think that's what's going to happen,” former royal chef Darren McGrady told Hello! magazine. “Meghan can join the royals at Sandringham at Christmas because she'll be engaged and part of the fold.”

Royal watchers will soon get their Prince Harry fix as he’s due back in the U.K. this week, according to People, to mark the 20th anniversary of his mother’s death. On Wednesday, he will join his brother and sister-in-law to tour Kensington Palace’s public garden and meet with leaders from the charities Diana worked closely with throughout her life.
