According to Alex’s invitations, Friday evening was reserved for partying and Saturday afternoon was for “recovery.”

An afterparty was also held at Montauk’s Common Ground.

On Sunday she looked back on the successful weekend via Instagram Stories.

“The vibes were really impeccable. Seeing women from all over the country come to chill, drink nice cocktails, get massages, swim, get infusions, eat nice food and make new friends, that was it.”

She added: “It’s epic how many of you came alone and left with a new group of friends.”

“I love you all. Let’s do it again soon,” the media personality wrote, before signing off with a winking emoji.
