"It's truly been the best party ever thanks to my husband," Trista tells PEOPLE of the bash held at Bol in Vail Village. "Believe me, there were happy tears at the party. I was in love with the fact that I knew everyone there."
Ryan planned the party for his wife, whom he met and proposed to on The Bachelorette's 2003 inaugural season finale. The two married in December 2003 and have two children, son Maxwell, 5 and daughter Blakesley, 3.
Guests toasted Trista with Martini & Rossi Asti cocktails as they enjoyed bowling and hit he dance floor with tunes provided by DJ Logic. Singer Brett Dennen, one of Trista's favorite performers, did a special set for the birthday girl.
"It was one of the top three best nights of my life!" Trista says, noting that last weekend, "Ryan whisked me away to Santa Barbara without the kids for a little getaway."
In lieu of gifts, guests were asked to donate to lovehopestrength.org, a charity that helps raise awareness fund cancer centers and increase bone marrow databases.
