Sounds like a fun fiesta! Lauren Conrad‘s past trips to Cabo San Lucas haven’t always gone smoothly—remember seasons one and two of Laguna Beach?—but her most recent visit was, well, paradise. The Hills alum, 28, jetted down to Mexico on June 19 for a four-day bachelorette bash with 10 of her closest friends, and Us Weekly has all the details on their relaxing trip.

Conrad posted several snaps from the weekend via Instagram, using the hashtag “#donttellmrtell,” a playful reference to her fiance, William Tell. But he needn’t have worried. The bride-to-be and her BFFs spent much of their trip sunning and sipping cocktails at the seaside Esperanza Resort.

“The trip was more about relaxing and taking time off than raging,” a pal reveals in the new issue of Us Weekly. Adds another source: “The activities were wholesome—for the most part!”

Which is not to say the ladies didn’t have fun. On June 20, the group partied past midnight at downtown club Squid Roe, where a witness spotted Conrad with a “huge white bow” on her head. “Her friends were trying to embarrass her!” the onlooker tells Us.
