Jenna Bush and fiancé Henry Hager celebrated their final moments of unattached life with respective girls-only and guys-only getaways this month, PEOPLE has learned.

Bush, 26, and a group of female friends headed to Florida in mid-February for a girls-only getaway. "She had her weekend ... in Boca Raton, but at a private home," a source tells PEOPLE. "It was like a spa weekend. It was very low-key."

The following weekend however, Hager, 29, and a group of male friends kicked off a bachelor party in Miami. "It was a total boy's weekend," says the source. "There were about twenty guys, most of whom came down from D.C. and New York. They went fishing all day Saturday, but they didn't catch anything!"

The group then headed to South Beach's Delano Hotel to continue the festivities. "They hung out behind the pool area at the hotel, behind the bar. He was having a great time," says the source, adding that Hager called it a night around 1:30 a.m., while some of his friends stayed behind.

As PEOPLE exclusively reported in January, the couple are slated to marry May 10 at the President's ranch in Crawford, Tex. A source says Bush and Hager – a former Commerce Department staff member who's in his final year of the MBA program at Virginia's Darden School – are considering "spending four weeks in Europe, going from country to country," for their honeymoon. But of course, wherever they go, they won't be alone: The Secret Service will tag along.
